Tochnog Professional

External Software



Pre-post only:

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.

Freecad is a free CAD program. Under active development by a community. A bit difficult to use.

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 + FEM calculations:

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.

Mecway is a finite element program. It is commercial, however extremely inexpensive. Tochnog Professional can read inp files from preprocessing in Mecway, and can write gmsh files for postprocessing in Mecway.

Welsim is a finite element program. It is commercial, however inexpensive. It enables quite typical finite element calculations, mostly mechanics.

Simscale finite element program in the cloud (in your webbrowser). It is commercial. Fluids, solids, etc.

Ansys is a commercial finite element program. A free academic version is available.

Abaqus is a finite element program. It is commercial, however an academic version is available.

Femap is a finite element program. It is commercial, however an academic version is available.

Sap2000 is structural design and analysis software. It is commercial. A trial is available.

Scia is structural engineering software. It is commercial. A free student license is available.



Other (theory, etc.):

SoilModels is an internet site propagating the use of advanced soil models. It is run by a group of leading researchers in the field of geomechanics.
