I am using Paraview 5.11.0 on a Mac Powerbook Pro running macOS Ventura 13.1.
I generated a Plot3D ramp.xyz file and a ramp.q file from my Fortran90 CFD code. The ramp.xyz file loads just fine and I’m able to display it. When I type the .q file in and click apply, I get the following errors.
ERROR: In vtkMultiBlockPLOT3DReader.cxx, line 2618
vtkMultiBlockPLOT3DReader (0x29ebe6760): File: ramp.q not found.

The ramp.q file is definitely there and I made sure all the read permissions were on. The ramp.xyz grid is no displayed. I attached both files. Pleae let me know what I may be doing wrong.

Hi @drmillman
No issues here, with pv 5.11 on Linux.
Best,

Does that mean you were able to open the attached files on Linux?

Then is the issue PV on macOS, or is it a permission issue on the Mac? How can I tell?

I’d suggest trying with another computer first.

I got it working on my Mac. Thanks!
