Calculix
With CalculiX finite element models can be built, calculated, and post-processed. The pre-and post-processor is an interactive 3D tool using the OpenGL API. The solver is able to do linear and non-linear calculations. Static, dynamic, and thermal solutions are available. Because the solver makes use of the abaqus input format it is possible to use commercial pre-processors as well. In turn the pre-processor can write mesh-related data for nastran, abaqus, ansys, code-aster, and for the free-cfd codes dolfyn, duns, ISAAC and OpenFOAM. A simple step reader is included. In addition, external CAD interfaces are available. The program is designed to run on Unix platforms like Linux and Irix computers but also on MS Windows.
