- CalculiX is a finite element method package for building, calculating, and post-processing field problem models.
- It includes an interactive 3D pre- and post-processor using OpenGL and a solver supporting linear/non-linear, static, dynamic, and thermal analyses.
- The solver uses Abaqus input format, allowing commercial pre-processors, while the pre-processor exports mesh data for various codes like Nastran and OpenFOAM.
- Developed by MTU Aero Engines employees in spare time, it runs on Unix, Linux, Irix, and MS-Windows.
