FLUIDS Dynamics simulation
CFD ANALYSIS

COMPASS has developed
a complete engineering software for

solving and simulating fluid flow problems (computational fluid dynamics – cfd), porous media flow, heat transfer and multiphysics.

Leading finite calculus (FIC-FEM) solver technology.

Robust, agile and optimized algorythm.

Highly reliable and accurate.

Tdyn Fluid Dynamics Package (Tdyn CFD+HT)offers six modules which can be integrated and coupled to achieve complex simulations.

3D FLOWS SOLVER
Features the latest technology for solving real fluid flows in 3D (transient or steady), including turbulence effects. The different fluid models allow solving the full range of fluid dynamics problems, including porous media flows.

HEAT TRANSFER
Offers an advanced solution to solve complex forced, natural, and mixed convection heat transfer in fluids and conduction in solids. Heat transfer module includes a conjugated heat transfer solver, including contact conditions with resistance effects.

TRANSPORT OF SUBSTANCES
Allows solving problems concerning the advection/diffusion of mass/species in fluids, including reactive effects. It is also able to solve species diffusion problems in solids (Fick’s law).

FREE SURFACE
Iincludes two advanced algorithms for solving problems with free surface, offering the most reliable solution for every free-surface analysis.

MESH UPDATE
Offers several mesh updating strategies: prescribed and free bodies movement with automatic mesh updating, explicit mesh movement via user functions and combinations of these strategies.

CUSTOM PROBLEM SOLVER
ExtendS the capabilities of Tdyn CFD+HT by offering different utilities for creating and solving new user defined problems, described by partial differential equations (PDE).
