Tochnog Professional

External Software



Pre-post only, Free:

Freecad is a free CAD program. Under active development by a community. A bit difficult to use, regularly bugs, and a bit chaotic.

Gmsh is a pre- and postprocessor. It is available for free. Tochnog Professional can read the mesh generated by GMSH, and write postprocessing files for GMSH.

Paraview is a postprocessor. It is available for free. Tochnog Professional can write vtk files for Paraview.



Pre-post only, Not Free:

Gid is a pre- and postprocessor. It is commercial, however free up to 10000 nodes. Tochnog Professional can read the mesh generated by GID, and write postprocessing files for GID. This is a fine program, easy to use, many options; recommended.



Pre-post + FEM calculations, Free:

Adonis is a free finite element program for geotechnical calculations, with a modern GUI. Tunnels, slope stability, etc. Isoparametric elements, structural elements, etc. Mohr-coulomb, modified camclay, etc.

PrePoMax is a free graphical pre- and postprocessor integrated with the free calculix finite element program. For pre-processing you need to use the CAD file from an external CAD program; then meshing can be done by prepomax. Clean and easy to use, recommended.

Analysis3D is a free finite element program for structural analysis. Easy GUI and calculations; includes norms (Eurocode etc.); import DXF files.

MFEM is a finite element program. It is free. Electro-mechanics and fluid dynamics. It specialises in large multi processor calculations.

Openradioss is an explicit FE program. It is open software. For simulating automotive crash and safety, shock and impact analysis, electronic and consumer goods drop testing, and fluid structure interactions.
