WHAT IS DIGITAL SIMULATION?

Example of results: Stress field maps.

It is a way of producing a virtual simulation of a product in its final environment and, thereby, meeting numerous industrial challenges, such as anticipating design pitfalls, reducing the number of prototypes and even encouraging innovation.

We can support you with our computation skills, either for a project you have designed or by incorporating it directly into the study you have entrusted us with.

  • Validating solutions using digital simulation: minimising risks at the design stage.
  • Simulating and anticipating the behaviour of a part, using a CAD file.
  • Lightening parts by incorporating lattice structures.
  • Redesigning a part where a fracture zone has been identified and/or optimising a functionality.

MECHANICAL SIMULATION

 

Mechanical results • Mesh • CAD

The aim of mechanical simulation is to anticipate the behaviour of an assembly or a component depending on external mechanical stresses: pressure, forces, pre-stresses, etc.

The objective may be to:

  • Dimension a geometry.
  • Optimise the geometry of a part, for greater strength and improved performance.
  • Choose a material for production depending on the specification’s constraints.
  • Examine the transfer of production technology.

TOPOLOGY OPTIMISATION

 

Topology optimisation of a “Linkage” connecting arm.

Topology optimisation is a cutting-edge technique, which enables material to be distributed over a part, leaving only the volume that is strictly necessary, while adhering to the load and strength constraints.

We are able to propose optimal geometries to closely match your operating constraints:  

  • Topology optimisation results in both an increase in strength, in accordance with the specification, and an improvement in performance thanks to a, at times considerable, reduction in weight.
  • There are numerous areas of application from the aviation to artistic sectors, including industrial and medical applications.

The benefit of topology optimisation means that it is possible to consider complex geometries that cannot be achieved using traditional methods.

THERMAL SIMULATION

Temperature field colour maps for a dissipater.

Thermal simulation allows us to anticipate heat transfers within a part and/or with the external environment. 

  • Measuring heat balances to analyse the temperature field, as well as the flows of heat in a steady or transient state.
  • Improving heat dissipation by extracting calories:
    • Optimising the thermal properties of tooling by means of conformal cooling.
    • Reducing the cooling time for parts or dedicated systems.
    • Maximising heat extraction thanks to conduction and/or natural or forced convection phenomena.

FLUID SIMULATION (CFD)

Velocity field maps for an injection mould cooling system.

Fluid flow simulations (CFD: Computational Fluid Dynamics) are based on algorithms enabling the behaviour of a flow, of air, water or any other fluid, to be analysed. 

Fluid simulation enables:

  • Load/pressure losses in pipes to be analysed.
  • Velocity fields to be viewed and pressure fields in the flow to be observed.

Improving the production cycle for a part is directly linked to the cooling time for the latter in the injection mold. Hence the possibility of combining thermal & fluid effects within the same simulation. This process is commonly known as conformal cooling.

This type of simulation is particularly suited to studying the heating of electronic components where cooling and insulation are required: heat sink, furnace, etc.
