ParaView doesn’t support CalculiX’s results (.frd) files but there are several converters to .vtk format available:
FreeCAD:
a) Import the .frd file
b) Select the Results object in the tree
c) Export to .vtk
note: FreeCAD’s FEM module currently displays results in SI(m) unit system and the conversion will also write the results in this unit system
CalculiX results 'frd' to Paraview 'vtk' converter - FreeCAD Forum
a) Download the executable from the Google Drive
b) Place the .frd file in the same folder as the one with mmh_ccx2vtk.exe
c) Open the command line in this directory and type: mmh_ccx2vtk file_name.frd
Thanks for this helpul tip!
I have trouble saving the post processing done in paraview. When I “Safe Data” as vtk and reopen the file, all the filters I had applied are no longer there.
Dear FEAnalyst,
let me first thank you and Matej for the outstanding work you are doing: Prepomax is getting really a professional tool. I have a small suggestion, out of the many I’m sure you receive everyday. Since now prepomax supports time harmonic analysis alongside multiple steps analysis, it seems to me that converting frd to vtk and getting advantage of the also outstanding Paraview, FreeCAD is no longer adequate, for it is unable to deal with many steps at once: Namely, you need to convert one step at a time, if I am not mistaken. Wouldn’t it be the right time to implement a streamline conversion button (which may call ccx2paraview) ? Is it troublesome to set up? Thank you, Andrea
I am not using ParaView for post-processing CalculiX results, and I am unfamiliar with the ccx2paraview tool. However, once the PrePoMax imports the results, the ccx2paraview tool will not help anymore since all results are stored in a different format. Exporting the data is not hard, but it requires time.
