CalculiX is a package designed to solve field problems. The method used is the finite element method.
With CalculiX Finite Element Models can be build, 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. Both programs can be used independently. 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 is able to write mesh related data for nastran, abaqus, ansys, code-aster and for the free-cfd codes duns, ISAAC and OpenFOAM. A vda CAD interface is available. The program is designed to run on Unix platforms like Linux and Irix computers but also on MS-Windows.
Calculix is a very powerful tool of analysis, highly configurable allowing the user to have COMPLETE CONTROL over the analysis, with more than 18 types of analysis covering most fields of study finite element Calculix’s user can modify any variable on the analysis at discretion, the huge amount of information and documentation on the web make CalculiX a great alternative for the development of research projects where computer tools must accommodate the needs of the study.
