Hey everyone.

I am simulating a transient analysis of a centrifugal pump using the sliding mesh approach (dynamic mesh) for my masters thesis. I am using the results of a steady state analysis as initial conditions for this transient simulation. I ran around 0.46 seconds (4.7 rotations of the impeller) and I am facing an issue when postprocessing the data in paraview.


First of all, I have this error when I firstly open the paraview:

 ERROR: In vtkOpenFOAMReader.cxx, line 8816
vtkOpenFOAMReaderPrivate (0x634e420): Number of cells/points in mesh and field do not match: mesh = 0, field = 13952 in Up, li { white-space: pre-wrap; }

Second, as you can see in the attached image, I have not an interpolated result for the velocity. Only the results in the centroids.

I believe this is due to the fact that I am using a sliding mesh. If anyone has any idea of why this might be happening, I would be truly grateful.

Best Regards,
Pedro Gouveia

Hey guys,

Anyone has any suggestion? I just ran the incompressibleFluid/propeller tutorial and the same thing happens. The error saying the number of mesh cells do not match and the fact that there is not an interpolated velocity. Just the velocity at the centroids.

Thanks in advance,
Pedro

I just found that 13952 (the number that appears on the error) corresponds to the number of entries that the "nonConformalError_*" (which is a patch that openfoam creates for non conformal coupling interfaces) has in the U file. However, when I delete those lines, I get another error:

Warning: In vtkOpenFOAMReader.cxx, line 9198
vtkOpenFOAMReaderPrivate (0x16f16c80): boundaryField nonConformalError_on_NCC2_3 not found in object U at time = 0.000537634

I think I managed to solve it. Basically I was using Paraview-5.12.0 (independent version from openfoam) and not the paraviewopenfoam510 that comes with OF11. I reinstalled OF11 with this paraview and everything is being read correctly now.
