So similar results but my observation is that the Properties panel only includes model components and not velocity, pressure etc. properties. And no orientation array options.

I must also repeat that only PV 5.7.0 allows me to open a file to edit without launching it from FreeCAD CfdOF and can’t save anything then.
Have you tried changing 'Case Type' on the Properties tab to 'Decomposed Case' (and then clicking apply). This will be necessary if you ran the case in parallel (it is set automatically when paraview is run from CfdOF).

If that doesn't work, from your version information it looks like you have a pre-release version of Paraview 5.7. Perhaps worth downloading the latest version and trying again.

Thank you again Oliver,

I did try that after your suggestion that also came from ParaView forum and obtained the following.

I actually managed to generate a clip and glyph that gave me thye omega pattern on the clip surface. Made great progress today and can make progress now. Key thing is I can now save and load states. I now need to spend some time obtaining my velocity glyphs. But your help is again greatly appreciated.

First off, this is now and edit. I hope I sorted the problem at 4:00am this morning. but here is the initial question.

Fantastic results since our last exchange but new problem I think. My model is larger again and it has worked very well untill about a week ago when it started to fail after a significant number of iterations. Please find attached reports but my Temp file now has may "mat-debug-###.log" files woth no content as well as teh attached.

Any suggestions please, I'm realy happy with the progress!

Sorry,

Had another look at 04:00am this morning and rebuild my model. Hope it's sorted the problem now as it approaches 5000 iterations after 5 hours and not sure what was wrong before. Sorry to trouble you!
