Our way of working

At Demcon multiphysics we strive to offer the highest quality engineering service tailored to each client’s specific need. Our technical consultants use a professional elicitation process to clarify the requirements and roots of the problem that needs tackling.

Our consultants have strong academic and industry background including simulation software vendors. They all have obtained master degrees in the field of science and engineering and at least a third have completed their PhD. This enables Demcon multiphysics to provide you with a competent consultant who possesses the relevant academic skills and experience.

We are able to quickly grasp most problems and propose a useful approach to shed light on the problem. This may be a numerical approach using simulations as well as a more pragmatic or analytical approach. After jointly defining work packages, a cost estimation based on an ongoing hourly rate or a fixed price quote will be prepared and discussed with the client.

Depending on the complexity and scope of the problem, we use a step-by-step approach to build-up the model to generate meaningful results. Naturally, interim results will be discussed between the client and our consultant to make sure we are progressing in the right path.

Projects are concluded with a PowerPoint based report or a more comprehensive written report if needed. Our results summary always comes with concrete conclusions and recommendations.

We prefer to work from our own offices but we understand that in order to kick-start larger projects spending some days between the clients engineering teams on your location can make the difference.

We take confidentiality very seriously and it is common for us to work with clients with a non-disclosure agreement (NDA) in place.

Depending on the topic, a large number of important choices have to be made when going through the simulation process. These choices have an effect on the outcome of the simulation and define whether it is an appropriate representation of the real physics.

Generally, the setup, execution and evaluation of simulations follows the following three steps:

1. Pre-processing
The product geometry or fluid domain must be divided into millions of elements for which the computer on an individual level will determine all required physics. Dividing the geometry into a large number of volume elements allows us to analyze any given product geometry. This, together with choosing the right type of elements, is called meshing. The quality of the mesh has influence on the accuracy, convergence and speed of the solution. Boundary conditions and material properties have to be added to complete the model. Specific conditions can be pressures, temperatures, forces or for example, velocities, all depend on the type of problem.

2. Solving
Once the model has been completed, the actual calculations to simulate the physics can start. Simulations can be ‘steady state’ or ‘transient’. A steady state calculation means that there is no time-dependency. This for example is often the case with mechanical stress problems as the forces are in equilibrium. Transient problems also have a dependency on time. The temperature rise profile from filling a cold mug with hot coffee is a good example of a time dependent case.

3. Post-processing
The results of the simulation, or parts of it, are visualized to ease evaluation. Contour plots, graphs and tables are created as required. The knowledge and insights which are obtained from the simulation are used by our engineers to confirm whether a product works as expected or whether adjustments have to be made. Preferably, a FEA/FEM (Finite Element Analysis), CFD (Computational Fluid Dynamics) or CEM (Computational Electromagnetic) calculation is made at an early stage in the development process as a good final design often requires a number of iteration.
Digitally we can make fast changes in the model, and evaluate its improvement on the performance of the real model. In this way we can make a lot of digital design iterations before making a (next) prototype, which can save a lot of time and money.

Partners and software

ANSYS is a global player in the field of computer-aided engineering (CAE), providing high-end pervasive engineering simulation software. Used for model preparation, (thermal) mechanical, thermal and fluid flow analyses.

Demcon multiphysics uses products from Mathworks to create dynamic simulations at system level. Especially Matlab and Simulink are used to perform LEM simulations.

Sorama offers unique high-resolution acoustic cameras to detect and analyze noise and vibrations. Their cameras use patented technology for visualization and localization of sound and vibrations.

COMSOL Multiphysics is particularly suitable for strongly coupled multiphysic problems. We specifically have extensive experience with the electromagnetic AC / DC and Heat Transfer modules.

3D CAD files of the product that needs to be analyzed are usually an extremely helpful starting point. On of our standard CAD tool is SolidWorks. Importing CAD files in different formats is usually not a problem.


The team of Demcon multiphysics consists out of highly skilled and motivated engineers with PhD and MSc backgrounds. Our engineers are specialized in the areas of heat transfer, fluid dynamics, process technology, electromagnetism and structural mechanical analysis. We enjoy combining our academic background with a pragmatic engineering approach. Offering our clients innovative solutions for design, development and improvement of products and systems in which physical and chemical processes play an important role.

Being part of the wider Demcon group, differentiates us from most typical simulation-only consultancy firms. We are part of a large engineering community (>650 people) and are able to draw upon a wealth of experience from specialist engineers and scientist in many technical disciplines.

If needed we can serve as a full service technology supplier, ranging from R&D to prototyping or series production and everything in between. This allows us to deliver the actual implementation of your product or system in addition to our expertise in virtual prototyping.

Being part of the Demcon group with over 60 M€ in annual revenue also gives us the financial strengths and comfort to deliver. No matter what, we’ve got you covered!

Demcon Multiphysics is ISO 9001:2015 certified. This means that we actively improve the quality of the projects that we are conducting.
