A coupling library and ecosystem for partitioned multi-physics and multi-scale simulations, including surface and volume coupling.

CalculiX examples by Prof. Martin Kraska from Brandenburg University of Applied Sciences. Excellent starting point to master parametric modelling with CGX and CCX.

CalculiX Advanced Environment is designed to guide you through the CalculiX keywords creation process and is aimed to help you reach the correct input file with no mistakes.

Various tutorial cases for the coupling library preCICE with real solvers. These files are meant to be rendered on precice.org, so don't look at the README files here.

CalculiX to Paraview converter (frd to vtk/vtu). Makes possible to view and postprocess CalculiX analysis results in Paraview. Generates Mises and Principal components for stress and strain tensors.

A python library for structural analysis and design

preCICE-adapter for the CSM code CalculiX

A multi-body simulation software

A library for creating and running 3D FEA simulations using the opensource Calculix FEA Package.

Pre- and Postprocessing for CalculiX can be done with this component in coreform cubit. The results will be converted to Paraview (.frd and .dat: nodal, element and integration points results).

Official and user examples for CCX and CGX. All in one place. Do not hesitate to add yours.

Gmsh to CalculiX converter (.inp to .inp)

Salome universal to CalculiX converter. Converts UNV mesh to the CalculiX INP format.

Coupling of OpenFOAM, CalculiX and Code_Aster for Conjugate Heat Transfer, using the multi-physics coupling library preCICE

Unified physics engine written in Rust, aiming to replace Bullet, OpenFOAM, LAMMPS, and CalculiX.

CAD/CAE Copilot — an AI-native CAD/CAE/CAX workbench for AI agents. Text-to-CAD, text-to-CAE, real build123d/OpenCASCADE geometry, editable parameters, stable topology pointers, deterministic critique, and MCP server tools.

Reader for CalculiX .dat files

Prool's modifications of CalculiX CrunchiX (ccx)

Salome to CalculiX mesh exporter: outputs Salome mesh to the CalculiX INP file.

Convert GMSH ABACUS .INP file to .INP file for CalculiX CGX
