Simulations

Structural and Thermo-Structural Simulations

We perform advanced static and dynamic structural simulations for a wide range of projects. Our experience includes:

Linear and nonlinear static analysis.
Dynamic analysis: vibration modes, frequency response and spectral analysis (SRSS).
Harmonic and random vibration.
Assemblies with multiple contacts.
Linear and nonlinear buckling failure modes.
Thermo-structural analysis.
Model reduction.
Design optimization.

Thermal Analysis

We build steady-state and transient thermal models:

Linear and nonlinear analysis.
Temperature-dependent material properties.
Heat sources varying with temperature, position and time.
Parametric radiation and convection modeling.
Design optimization.

Fluid Dynamics Analysis

We carry out steady-state and transient fluid dynamics studies using CFD tools, with experience in the following models:

Steady-state and transient models.
Compressible and incompressible flow.
External and internal flow.
Flow with heat transfer.
Conjugate heat transfer (CHT).

Dynamic System Modeling

We simulate dynamic processes by modeling systems of different kinds. Mechanical, thermal, electrical, hydraulic or pneumatic phenomena can be simulated, and even coupled together.

These models enable system behavior optimization while eliminating the cost and risk of experimental testing.

They are also an ideal complement to the design process, since they allow predicting, controlling and comparing the behavior of different design alternatives or operating points of a system.
