Engineers | Numerical Simulation | ANSYS

On a daily basis, DAES teams contribute to the definition of advanced engineering solutions through equipment and component simulation. Working closely with the customer’s project teams, we take charge of model definition, studies, optimization iterations, scenario analysis and the development of specific tools or methods that can be used for future evolutions.

Our teams are involved in the study of all physical/multiphysical phenomena : mechanics, fluidics, thermics, optics, electromagnetism, dynamics, seismics… and carry out numerical simulations with ANSYS, ABAQUS to predict a system’s behavior numerically (i.e. by minimizing or even eliminating long and costly physical test phases).

In the words of Cyril Kharoua, CEO of DAES: “At the beginning of my career, we had this saying that nobody believed in digital simulations except the person who did them, and that everybody believed the test except the person who did it… today it’s almost the opposite!”

Watchmaking

From linear static analysis in small deformations to non-linear analysis in large deformations using materials with plastic or hyperelastic behavior, taking into account complex contacts between parts, mechanical analysis is at the heart of our business. The numerical representation of experimental mechanical tests (bending, compression, tension, etc.) in the form of numerical simulations will enable you to evaluate the performance of your products and optimize their behaviour while substituting materials, adding coatings or improving geometry.

Our specialized engineers provide you with their expertise and sector-specific knowledge, using state-of-the-art tools: ANSYS, ABAQUS, Code_aster, etc.

Discover

Thermomechanical studies are used to model deformations and mechanical stresses due to thermal expansion in your systems. This type of numerical simulation helps identify critical areas and optimize performance.

Still based on the finite element method, numerical simulations model the behavior of materials, whether metallic, ceramic or composite structures.

On the basis of the simulations carried out, our engineers work with your project managers to identify possible improvements to your design project, using reference software such as ANSYS, ABAQUS and …..

Discover

CFD covers all numerical methods used to model the flow of liquids, gases and other complex fluids. Our engineers can help you develop projects where aerodynamics, thermics (heat transfer, cooling), turbulent flow effects or coupled fluid-structure interaction (FSI) effects require advanced modeling.

Whether you need to design the best mesh or implement an advanced turbulence model, we’ll use state-of-the-art software to simulate your needs: ANSYS CFX, FLUENT, OpenFOAM, MODELICA.

Discover

Dynamic effects in mechanical systems are often neglected and complex. We distinguish between implicit and explicit analyses: 2 types of modeling that enable our engineers to check the design and performance of your mechanical structures at different timescales and for different phenomena.

Our expertise in the application of finite element methods and in structural dynamics, from linear -spectral- to nonlinear -materials (hyperelasticity or plasticity), we are able to help you meet the design challenges associated with using state-of-the-art numerical tools (ANSYS, LS-DYNA, AUTODYN, ABAQUS, code_aster).

Discover

Electromagnetic analysis is essential to the development of motors and, more generally, mechatronic systems such as transformers, sensors and actuators. Electrostatic, magnetostatic and electromagnetic transient analyses help optimize efficiency, sensitivity to disturbance and compliance with safety standards.

By coupling with thermal and mechanical analysis, our customers benefit fully from the multiphysical simulation capabilities offered by our engineers. For your electromagnetic simulations, we use ANSYS-Maxwell in particular.

Discover

Process simulation enables us to model a complex system in its entirety, taking into account the interaction of its components. The behavior laws of these components are simplified and take into account a wide range of their operation, enabling simulation of the entire system life cycle. Thus, these process simulations (known as “1D” or “0D” at the level of each component) are essential complements to 3D simulation for integrating all design stages. Our engineers will support you with the most modern tools adapted to your needs: EcosimPro – Librairy CryoLib, OpenModelica, Model-based design, SimCryogenis, SUMO).
Discover

Today, there are a number of industry-specific solutions that enable advanced studies to be carried out for different segments of a product’s design cycle. These tools don’t always talk to each other, and the sometimes heterogeneous data is rarely usable without reprocessing.

Our specialized engineers support project teams in mapping out the engineering process, analyzing the tools used, benchmarking market solutions, drawing up functional specifications, and developing scripts or apps with Python, enabling the transfer of information in the development cycle.

Discover

Optical simulation is an essential foundation for innovation in many fields. It offers our customers a unique opportunity to better understand and explore concepts, and to observe phenomena that would otherwise be inaccessible to direct observation. Our teams of engineers work with a variety of players in a wide range of sectors to bring their complex projects to a successful conclusion.
