i just found an interesting new project at GitHub, is a patch for CalculiX to VTK output formats. did not try yet, since i’m not expert in deployment.
CalculiX has many supported mesh format to export (e.g Nastran, Code_Aster, etc) but none for another output results format. even a few exporter available out there, still may useful if done inside CalculiX.
hope it will be officially supported for the next future release.
Thanks a lot @rafal.brzegowy for your work, have tested and saddly none of the result VTK files can be opened in Salome Paravis. For a no lineal case it gives me an error “vector too long”, and for a basic lineal test it open the file, but none of the field variables are available. Should the input file be modified to produce valid VTK results?
