There are many reasons a company might choose consultancy as the way to couple simulation to the design process, rather than take the software purchase route. SSA has a long track record with simulation projects of all types. A simulation project has many aspects, needs many decisions to be made, and delivers its benefits in a variety of ways.

At SSA we like to work collaboratively, ensuring that the customer understands what we did, how we did it, and what we think the simulations tell us. If we do that that customer gains the maximum from the project and critically; if a software purchase is seen as a sensible next step, this knowledge has already been transferred to the customer. Projects need a set of well defined aims, relevant and useful input data, and a thought out way of applying the results in a realistic manner.

SSA have been involved in simulation for many years, and have the experience to help at the project definition and planning stage, and can interface with a customer customers, helping to ensure that the delivered project provides the information and deliverables required by the project.

Simulation Engineering

Structural analyses can be linear using simplifying assumptions, or consider non-linearities such as contact, plasticity, shape change or dynamics. This allows us to determine what the resonant frequencies are, and how externally applied loads and inputs drive these resonances.

The dynamic response can be plotted in ether time or frequency domains, and the likelihood of structural failure assessed. This allows us to determine flow velocities, pressures and temperatures in a wide variety of situations. We have also carried out numerous projects where the efficiency of rotating turbines and impellors was investigated using advanced moving mesh approaches. Thermal Analysis : How heat travels through and around an object will often play a critical part in its operation.

Heat sink design is one area in which SSA has extensive experience, however thermal management is an area which simulation has much to offer. Crash and Droptest : Modelling rapid events, which often result is extreme behavior, is generally undertaken using an explicit solver. This technology has been used for many years in mainstream aviation, marine and automotive industries, however it offers many opportunities for novel and innovative simulations in less traditional marketplaces.

From fully coupled thermal structural to highly challenging fluid structural interaction, SSA has a wide experience of applying these techniques in real industrial scenarios.

Composites and other materials : SSA has extensive experience in the simulation of composite structures, considering both the usual deformation and stress behaviors, and the critical delamination and debonding effects which in many cases limit the realistic performance of these structures. Other materials such as polymers, elastomers and even metals need accurate definition, especially in highly demanding applications and projects which investigate the impact of this material response can be extremely useful in product development projects.

SSA has widespread experience of both parametric and non-parametric optimisation techniques, using either TOSCA for topology and shape optimisation and Isight for parametric type studies.You have needs in Numerical Simulations and would rather not open a full-time position for this task. One economical solution is to contract simulation specialists directly. You want to learn using open-source tools and integrate them into the conception process.

Subcontracting to Idra Simulation the verification of the structural design calculations using FEA, has been fast and efficient.

It gave us the suitable results in order to fulfill the current regulations. Our collaboration with Idra Simulation really helped us during the conception phase, saving costs and optimizing our design.

We expect to cooperate again in the future. Fast and professional service. Simulations helped us to better know our product and to open new ways of improvement. We are very satisfied with the results. The simulations performed by Idra Simulation assisted us in the development of a new industrial process with a high technical level and helped to shorten the prototype phase.

Idra Simulation provided us with expert detailed analysis and was very insightful with answers to many of our questions.

We are looking forward to the opportunity to work with them again in the near future.In many manufacturing-related industries, Mechanical Engineering Simulation tools like Finite Element Analysis and Computational Fluid Dynamics are used as an aid in product development.

They are used in various design phases to predict baseline performance specs, design around potential failures, and establish warranty strategies. A recent trip to the United Arab Emirates highlighted opportunities for contemporary engineering practices in a very traditional place. Traditionally, Architecture, Engineering and Construction AEChas had a slower adoption rate of engineering simulation software when compared to other manufacturing-based industries, such as Aerospace and Automotive.

We believe there are a number of potential reasons for this:. Despite these potential reasons for slow adoption rates, simulation is being deployed in the AEC market more and more. As mentioned above, many buildings are large and complex structures that are simultaneously static and dynamic. A building is both a fixed structure but those that occupy and use the building also turn it into a functional object. Simulation can be used to make the structure more aesthetically pleasing and functional for those who occupy the space inside and outside.

Listed below are some example mechanical engineering simulations applied to Architecture and Construction:. When the population grows, so do the buildings! In fact, Dubai boasts 12 of the 50 tallest buildings in the world, including the Burj Khalifa, which is the tallest at 2, ft tall.

Calling features

Enjoy some of the beautiful pictures below and just imagine what kind of simulation is utilized to ensure these buildings are as safe and comfortable as they are tall and beautiful! Think simulation can help your team build taller, smarter buildings in less time? Simulation in Architecture, Engineering, and Construction.

Simulation Consultancy

Slow to Adopt Traditionally, Architecture, Engineering and Construction AEChas had a slower adoption rate of engineering simulation software when compared to other manufacturing-based industries, such as Aerospace and Automotive. We believe there are a number of potential reasons for this: A "Build Quantity" of One - Every building in the world is unique. As a result, there is a limited amount of knowledge you gain from the simulation of a building, which can be leveraged for the next one.

Many Teams with Many Goals - A building is much more than just a single system. It is truly a system of systems. In many cases these systems are designed by separate teams, each with their own separate goals in mind. Unfortunately, a lack of efficient communication can result in a lack of alignment with respect to design and analysis techniques. For buildings especially very tall ones like the Burj Khalifa pictured belowthis is unbelievably high. As a result, the simulation model must be simplified to keep computing requirements economical.

This means more time spent on pre-processing, and a higher cost-per-analysis. In addition, simple conservative wind calculations can be made with paper and pencil, negating the need for CFD. However, architectural design trends are pushing buildings towards more complex and efficient shapes.

Design for Adjustment - One might think buildings are static, but in fact they are very dynamic. In a way, they act like tall living, breathing machines, that live for a very long time! As a result, they must be built for adjustability, to account for changing environmental conditions and use cases overtime. With adjustability in mind, an "optimized" design is not necessarily a design outcome. Long Design-Build Cycle - Buildings can take years, or even decades to build, including large teams of people who come and go along the lifecycle of the project.

Without a sense of urgency, perhaps deploying "highly sophisticated" tools, may not be regarded as a necessary expense. In most contemporary manufacturing processes, differences between CAD data and manufactured parts are thousandths of an inch. However, in construction tolerances are measured in inches, or even feet, depending on the application.

Quickly Adapting Despite these potential reasons for slow adoption rates, simulation is being deployed in the AEC market more and more. Newsletter Signup.

S Prev.Feedstocks do not develop at sufficient yield, land is not available and affordable, processing technologies fail to achieve the required levels of efficiency, from front end processing to final-step fuel finishing, or policies and finance do not support the sector. These are just a few of the main issues the biofuel industry faces these days.

Biofuel power

New technologies are developed every day trying to achieve that extra yield in a stage of the process that would make it profitable and less dependent on subsidies. These are just a few of the main issues the biofuel indu stry faces these days. These virtual prototypes will provide you with a detailed insight of you process efficiency in terms of mechanicalthermalfluid dynamic and chemical performance.

PRE Technologies has very relevant experience in CFD analysis of different biofuel production stages where processes were optimised early in the design stage, as well as FEA simulations where tanks, valves, heat exchangers and mixers were calculated in order to obtain their mechanical and vibrational performance limits. We follow standards and design guidelines of the UK environment agency, OFGEM and the department for environment, food and rural affairs.

We want to make sure our delivered solution will be implementable at an industrial scale complying with all regulations. A wide variety of vegetable and animal fats or oils are used to produce biodiesel. A number of thermal and chemical processes are used as well to promote esterification and transesterification. Finally, different batch or continuous processes are used to separate by-products such as glycerol and methanol to obtain further diesel purity.

All these different factors make the biodiesel production a very complex process and make every biodiesel plant different in its needs and technical challenges.

On the feedstock pre-treatment stage, mechanical filtration and separation can be evaluated using CFD analysis. Flow analysis to avoid stagnation areas and filter fouling can be performed, as well as water content removal studies.

From simple batch process reactions using catalysts to more advanced continuous processes such as fixed-bed, ultra-high shear, supercritical or ultrasonic reactions, simulation and mathematical modelling can provide critical reactor design information. Finally on the purification stage,the different by-products are separated and the techniques used and order of separation is process-dependent. Biogas is mostly produced as landfill gas LFG or digested gas.

However there is a large variety of processes, such as meso and thermofilic digestions according to the feedstock used as well as the type of final and by-products to obtain.

No matter the technology used, mechanical, thermal and fluid dynamical simulations can speed up the design process and help you find the root causes of the failures during operation. For the pre-treatment processes such as screening, maceration and pasteurisation, PRE Technologies can provide simulation services ranging from stress and vibrational analysis of maceration equipment to fluid dynamical analysis of the different pasteurisation processes to identify potential improvements in terms of efficiency and reliability.

Digesters vary significantly depending on the feedstocks used, the process thermo or mesophilic and the final products to obtain. Mixing, temperature homogeneity and equipment air tightness are of paramount importance. Again, fluid dynamic analysis can be used to understand the process parameters and make sure mixing, temperature and fermentation are optimised to get the maximum process yield.

Gas and liquid multiphase models can be used to determine the best tank geometries, mechanical agitators and thermal conditions even before the detailed plant design has started.This course provides an in-depth practical and structured understanding of the most important technical aspects of CFD simulation which are the basis for robust CFD solutions across a broad range of application areas.

The course is broken into two parts. Part one recaps the fundamentals of CFD and serves as an introduction to those taking up CFD and a refresher to experienced users. In particular, part one focusses on the wide range of turbulence models available in CFD software — how and why and when to use these models.

Request Full Details.I got lucky I think! Computational Fluid Dynamics CFD is a set of similar methods, but better suited for solving fluid-flow problems. This makes solving them quite impossible, at least at our current knowledge level honestly, my level does not allow for solving even the simpler ones.

This is technically true, but if you use such methods correctly you will get tremendously accurate outcomes!

No worries, we can get through them quite easily really! Usually, engineers use FEM in structural, heat transfer, and electromagnetic problems. Two professors at my Uni were writing a solver that used this method, but sadly I never got interested in the field. You divide the domain into particles, and then you describe how those can interact with each other. This is a really cool method if you want to check how a material will discharge from a silo since silos store granulated stuff.

Pretty nice huh! I completely get that! Imagine you have a bracket like that, and that you want to know how the stress goes through it:. This way you can actually establish how the stress field looks like!

You used Finite Element Method applied for a practical problem — this is what people reference as Finite Element Analysis! However, some methods will solve one set of tasks more effectively than others.

I think that the trend is obvious:. Finite Element Analysis FEA is a mathematical approach based on the Galerkin method that allows you to nicely solve a lot of structural problems including heat transfer and electromagnetism. You can of course mix the solution schemes for various problems, but the above seems to be the most popular approach. I think that this is a really important question… if you want to learn FEA.

But what does this means in practice? Finite Element Method FEM refers mostly to complex mathematical procedures used in your favorite solver. Think about it like a theory manual, lots of equations and mathematics. Sadly, there are far more FEM books than FEA books, but it is obvious that practical application will attract a lot of interest… so many of the FEM books started to use FEA in their titles simply to boost sales while still being only mathematical and theory manuals.

This means that FEA should refer to practical problems, but often may also point out to theory depending on the source. However, my friend made his Ph. They are simply completely different! If you want to learn more, you can read an article I wrote on this topic! You can read about my FEA story here. I can only imagine it offers the same amount of bang if you are good at it!

I mean, this is useful stuff with all the valves, airplanes and ships. There is definitely a place for a CFD specialist in the market. I think it mostly depends on what you can do with it. There is simply too much of this stuff. For the last 10 years and a Ph. I worked mostly on the shell and other thin elements stability. This is what I specialize in, and being a specialist really helps to spread your wings!

You can of course, just as I can.I talked to visitors who used other tour companies and they often had missed connections and invalid vouchers, so I am very grateful that Nordic Visitor is such a high quality company - I shared the contact info for Nordic Visitor and Larus, so my friends will have a better experience on their next tour.

Thanks very much to Larus and everyone at Nordic Visitor. You made this adventure fun, easy, and unforgettable!. I would highly recommend Nordic Visitor to any potential clients.

Overall we had a fantastic holiday, helped a great deal by the good weather. We had planned for a lot of rain, but we just followed the sunshine around the country. Moving on every day or two was quite hard work but because of doing that we saw a lot of the country - which we loved. Everyone we met was so friendly and enthusiastic, keen to talk to us and to tell us about themselves. The fact that everyone spoke perfect English took a lot of the stress out of a foreign holiday and we would both love to be back there right now.

The quality of the sunshine and the air was quite exceptional, the long sunny evenings were a bonus and the lack of crowds made such a pleasant change from England. The organisation of the holiday worked well, with trains, boats, planes and hotels all linking up well. In most cases we managed to walk from our hotels to railway stations. We appreciate all the efforts Bjarni went through to make sure that our tour was very enjoyable.

We had many upgrades and I believe that Bjarni was instrumental in making those happen. Both trips with Nordic Visitor have been beyond expectations. They will always be my first choice for traveling in the Northern Countries.

Overall, we were very happy with Nordic Visitor, especially with the itinerary materials we received on arrival and the seamless experience we had from arrival to departure. The Garmin GPS we received with our car was very helpful, particularly in locating hotels and other necessities. Thank you for the good map with all the suggested stops. We especially liked the homemade ice cream. All the travel documents were well organized, and we really appreciated your suggested stops and highlights.

We loved all the waterfalls. Everything was as expected or better than expected. The list of possible extra activities was very helpful.
