NUMERICAL
An essential step in product development
The finite elements expert allows, through its virtual prototypes, to evaluate product performance, to detect potential failures, to determine product reliability, help reduce development costs, streamline the initial steps of production.
At PRECICAD, you will enjoy an enviable expertise in the use of finite elements, issued by experts aware of issues surrounding product development.

Behavior of a structure subjected to critical loadings for analysis of the assemblies and non-linear behavior of hyperelastic & visco-elastic materials in large deformations.
Behavior of a structure in time under the influence of the mechanical actions applied to it, with variations of the boundary conditions.
Behavior of isotropic and orthotropic standard materials and materials capable of withstanding permanent deformations (plasticity) or demonstrating complex behaviors (nonlinear elasticity).
Behavior of a structure subject to a critical compression force or combination of forces that creates instability.
Analysis that predicts the life of a structure subject to cyclic loading or vibration.
Behavior of a structure following a mechanical oscillation movement around a stable equilibrium position or an average trajectory. The structure may be subject to sustained or transient excitation.
Optimum material distribution in a given volume subject to constraints.
Analysis of thermal energy transfers due to temperature differences in a control volume. In steady state, the analysis determines the thermal conditions of the body when it reaches thermal equilibrium. The time needed to achieve this balance is not studied. Under transient conditions, the analysis determines the thermal state of the body at different time step.
Analysis of the heat exchange between a surface and a mobile fluid on contact. The fluid particles act as carriers of thermal energy. Natural convection occurs when a gradient induces motion in the fluid. Forced convection is caused by an artificial circulation (pump, turbine, fan) of a fluid.
Analysis of the heat exchange from one point to another thanks to the interaction of the atoms or molecules of the matter without setting the material in motion. If the temperature in a solid varies from one point to another, the transfer of thermal energy is made from the high temperature zone to the low temperature zone, so as to establish an equilibrium.
Analysis of heat exchange by means of electromagnetic waves. Unlike conduction and convection, electromagnetic waves travel in a vacuum, no medium is needed for radiation transfer. The effects of radiation are greater at higher temperatures.
In electronic design, thermal simulation plays an increasing role as the power of the devices increases. The electronic boxe plays an important role from the thermal point of view because it determines the air circulation modes and therefore, the greater or lesser ease with which the components can be cooled.
Flow and thermal comfort analysis for HVAC (Heating, Ventilation and Air-Conditioning) systems.
Analysis of flow of an unbounded fluid over a surface or flow when the fluid is completely bounded by solid surfaces in steady (no change at a point in time) or unsteady state (variation in time).
Analysis of flow where the density of flowing fluid remains nearly constant throughout (e.g., liquid flow) or flow where the density of fluid changes during flow (e.g.,high speed gas flow).
Analysis of flow of high viscosity fluids such as oils at low velocities (ordered fluid motion characterized by smooth layers of fluid) or flow of low viscosity fluids such as air at high velocities (highly disordered fluid motion that typically occurs at high velocities).
Flow analysis with a free interface between air and water, as in a river. The analysis extends for a study of flows of a fluid comprising several phases. We can for example study the behavior of a fluid with gas bubbles, or study the behavior of two immiscible fluids in a pipe.
Analysis of the behavior of a system constituted by two mechanical entities considered as distinct: a mobile structure (rigid or deformable) and a fluid (flowing or at rest) around or inside the structure. The field of application of fluid / structure interactions is not naturally limited to aeronautics. For example, the problems of holding a bridge or a building under the action of the wind, water flows around the piles of a deck or the hull of a ship, oscillations of liquids in tanks or ducts ...
Analysis of the behavior of a system constituted by two mechanical entities considered as distinct: a thermal source (transfer by conduction, convection or radiation) and a fluid (flowing or at rest) around or inside the thermal source.
Analysis of the behavior of a system constituted by two mechanical entities considered as distinct: a thermal source (transfer by conduction, convection or radiation) and a solid (deformable or not) around or inside the thermal source.
