[OpenFOAM] Number of cells/points in mesh and field don't match

Excercise · March 15, 2019, 02:15

Hello,I am a beginner in OpenFoam.
After blockMesh, snappyhexMesh and simpleFoam, I opened paraview to deal with it ,but there was an error:
ERROR: In C:\bbd\ecd3383f\build\superbuild\paraview\src\VTK\ IO\Geometry\vtkOpenFOAMReader.cxx, line 7601
vtkOpenFOAMReaderPrivate (0000023B9F014E20): Number of cells/points in mesh and field don't match: mesh = 327073, field = 941192
I want to ask for some help with it. Thank you!

Hi,

It seems somehow ParaView reads old mesh, while simulation is run on the new mesh, with larger number of cells. Did you utilise -overwrite flag, when generated mesh with snappyHexMesh?
