How can I export a model diagram with stress analysis as an OBJ model file?

[COOLEST-GET]

result = mapdl.result
result.plot_principal_nodal_stress(0, 'seqv', background='w', show_edges=True, text_color='k', add_text=True)

The following code for exporting obj can only export the basic model, and I want to export the model with stress analysis to obj format

pl = mapdl.vplot(quality=5, return_plotter=True)
pl.export_obj("C:/Software/Qt_Project/demo6/ansys_module/new_model")

Hi.. I'm not sure if pyvista plotter can store these results in the obj file. Please do ask in their repository https://github.com/pyvista/pyvista

Thank you very much for your answer. I asked about the obj file format because I have finished parsing and loading the obj file of the basic model. But at present, I have not thought of any way to export the model with stress analysis as some model data for me to call in other software. Thank you again for your answer!

Hi @COOLEST-GET is there some restriction that you must use obj format? It does not seem to include generic field data like stress at each vertex:

you might need to export the information in different files... one OBJ for the VTK model, and another file (txt or picke) for the numpy array with the stresses.
