For example, the tutorial ‘incompressible/simpleFoam/motorBike’ shows non-zero velocities on the surfaces of the pilot and motorbike, when it should instead show zero.
Specifically, this is visible when only the patches for the
motorbike are selected in the
Mesh Regions entry, without the
internalMesh being selected.
The boundary condition
noSlip is not properly interpreted by VTK/ParaView,
which results in VTK/ParaView assuming that this is a zero-gradient boudary
This boundary condition was introduced to OpenFOAM in commit ab3081aa6bb and it is not yet supported in VTK/ParaView.
See the first bug report in OpenFOAM Foundation’s bug tracker on this topic, namely issue #2298.
Note: This should be fixed when the following report is solved: Issue #16873 in VTK’s project
The simplest workaround is to run:
and open the
VTK\*.vtk files in ParaView, in order to have the correct data
