CFD Commercial Software FLUENT, as a common CFD software package, is used to simulate complex flows from incompressible to highly compressible. With various solution methods and multi-grid acceleration convergence techniques, FLUENT is able to achieve the best convergence speed and solution accuracy.
Code_Aster is FEA simulation software developed by EDF from France, solving 3D thermodynamics, statics, structural mechanics, material mechanics, linear and non-linear dynamic problems.
OpenFoam is a CFD software similar as Fluent and CFX. OpenFoam can solve incompressible and compressible fluids with simple, piso and pimple methods.
