The native parallel Nek5000 file reader of Paraview 5.13.2 works well when the mesh is static. It seems by default, it reads the mesh from the first timestep and never updates it again. However, when we have a dynamic mesh (rotation, refinement, etc), only the first timestep is shown correctly and from the second timestep onward, the fields look strange as the mesh information is no longer valid. Is there an option, to force re-reading the mesh at every new timestep for Nek5000 reader?
@mwestphal sure, I’ll try to create a smaller version of this to share. I think if there was an option to read the mesh per timestep, everything else should be fine.
Nek5000_dynamicMesh.tar.gz (3.5 MB) @mwestphal I have attached a small 2D case. The mesh is refined from timestep 1 to 2, the first timestep is shown correctly as the mesh is loaded from the first timestep. The second timestep looks strange as the mesh is cached from the first timestep which is no longer valid
