CalculiX

CalculiX offers a robust solution for engineers needing to solve complex field problems using the finite element method. This package allows users to build, calculate, and post-process finite element models with ease. Its interactive 3D pre- and post-processor utilizes the openGL API, making it highly versatile.

The solver supports linear and non-linear calculations, providing static, dynamic, and thermal solutions. With compatibility for the Abaqus input format, it integrates seamlessly with commercial pre-processors. Additionally, it can export mesh data for various platforms like Nastran, Ansys, and OpenFOAM.

Designed for Unix and Windows, CalculiX is the result of dedicated development by MTU Aero Engines' team. It includes a simple step reader and external CAD interfaces, enhancing its usability. Whether you're analyzing jet engines or other complex structures, CalculiX provides the tools needed for precise and reliable results.
