Calculix Description
CalculiX allows you to build, calculate and post-process Finite Element Models. The interactive 3D tool for the pre- and after-processor uses the openGL API. The solver can perform linear and nonlinear calculations. There are solutions for static, dynamic and thermal problems. Both programs can run independently. The solver uses the abaqus format for input, so it is possible to use pre-processors from commercial companies. The pre-processor can write mesh data for nastran abaqus ansys code-aster as well as the free-cfd-codes dolfyn duns ISAAC OpenFOAM. Included is a simple step reader. External CAD interfaces can also be used. The program can run on Unix platforms such as Linux and Irix but also on MS Windows.
