OpenFOAM

OpenFOAM is the leading free, open source software for CFD, owned by the OpenFOAM Foundation and distributed exclusively under the General Public Licence (GPL). The GPL gives users the freedom to modify and redistribute the software and a guarantee of continued free use, within the terms of the licence. OpenFOAM was created by Henry Weller in 1989 under the name “FOAM” and was released open source as “OpenFOAM” by Henry Weller, Chris Greenshields and Mattijs Janssens in December 2004.

Using Workbench for your product development simulations will result in higher productivity from integrated applications leveraging common and compatible data models. Workbench gives you access to multiphysics and systems level insights that could not be attained before.

FEATFLOW

FeatFlow (Finite Element Analysis Toolbox for Flow) is a finite element CFD Fortran code using a very efficient FEM discretization together with a geometric multigrid approach for solving linear systems. This results in a very fast and computationally efficient solver, typically yielding a magnitude or more of speedup compared commercially available solvers. FeatFlow can be used from MATLAB with the FEATool Multiphysics GUI interface.

Features:

• CAE
• CFD
• Finite element
• Simulation

Code_Aster for Windows

Code_Aster is a free software for numerical simulation in structural mechanics, developed mainly by the “Advanced Mechanical Analysis” department of EDF‘s research and development department (ERMES, ElectRo – MEchanics Studies). Since Code_Aster is provided for Linux environment only, we chose to rebuild it from sources to share its Windows binaries as many users were asking on the forum.

Features:

• FEM
• Finite element
• Simulation
