Numerical simulation

CFD, acoustics, thermal, vibration, fatigue, static, dynamic: we validate and optimize your designs through computation.

What we do

Our scope of work.

A modular engagement: we can cover all or part of these areas while staying aligned with the rest of your project.

01

Static & Dynamic

Analysis of stresses, deformations and displacements under steady loads or transient impacts, to guarantee the integrity of your structures.

02

Fluid dynamics (CFD)

Modeling of internal and external flows, pressure drops, aerodynamics and mixing, to optimize your fluid systems.

03

Acoustics

Study of sound wave propagation and vibration loads, to reduce noise and improve comfort in use.

04

Modal

Determination of natural frequencies and vibration modes, to avoid resonance and secure dynamic behavior.

05

Thermal

Simulation of heat transfer (conduction, convection, radiation), to control temperature rise and optimize cooling.

06

Fatigue

Assessment of part lifespan under cyclic loading, to prevent progressive failure and make the product more reliable.

When to call us

Validate and optimize before you manufacture

“I want to lighten my part or cut material costs without risking breakage.”

We run static and fatigue analyses to spot oversized areas, optimize wall thicknesses and safely remove unnecessary material.

“My product or equipment runs excessively hot, or overheats in use.”

We simulate thermal and air flows (CFD) to size the heat sinks, optimize airflow or fluid injection and rule out any risk of thermal failure.

“My part or structure suffers abnormal vibration, noise, or fails early.”

Through modal, dynamic and cyclic fatigue analyses, we pinpoint resonance or stress concentration so the geometry can be corrected before it reaches the field.

“I want to validate the strength of a complex mechanical concept before launching prototype manufacturing.”

In some cases, numerical simulation can replace repeated physical prototype campaigns. We test your parts virtually under extreme loads to validate the concept at the study stage.

The Polytechnia advantage

Computation that feeds the design, not just colorful pictures

From simulation result to concrete change

We do not hand over a mere analysis report. Because we master CAD, design and manufacturing processes, we feed the findings straight back into the 3D model to correct and optimize your parts right away.

Realistic assumptions, grounded in the field

A simulation is only worth as much as its boundary conditions. Our expertise in electronics, integration and materials lets us set precise assumptions (loads, temperature gradients, manufacturing constraints, material anisotropy) that stay close to reality.

Far fewer prototype loops

By coupling simulation with design and manufacturing preparation under one roof, we cut down costly physical back-and-forth. You move from the virtual model to a working prototype with far better odds that it delivers on the very first part.
