Hello,
I’m having an issue with saving data created with the CfdOF add-on in FreeCAD. After my simulation finishes, I can open the data in ParaView just fine. However, I have been unable to save it in such a way that I can open it again to view later.
I tried saving as a .cgns file writing all time steps, but when I open the group of files again, all of my data relating to fluid velocity, pressure, etc. is missing. When I save without writing all time steps, I am locked at time step 0 even though the correct number of total iterations is displayed and I selected the time step I wanted. It also says “max is 0” in the Time Manager “VCR” controls. The 3D model loads, but with no CFD data.
I also tried the Save State option (as a .pvsm file) but it doesn’t work either. It only shows time 0 with no option to select the time step I actually wanted to save. It also only displays 0 iterations. The model will not load (presumably because it’s locked at iteration 0) and the workspace is blank. It does, however, show the pressure data I wanted to preserve when I saved the state.
How can I save my CfdOF data in ParaView so I can open it later to see the 3D model and associated fluid data? Any help with this is very much appreciated.
