Hello,

I've had a look around the forum but cant find anything on how to show the visualise the refinement levels of the mesh in Paraview.

I use snappyHexmesh with many refinement levels and would like to show levels (hence cell size/volumes) in paraview.

Does anyone know a good way of achieving this?

Many thanks,
Martin

Martin,



Hello! I hope all is well. It seems this is a late reply, but hopefully this response can help any future individuals who have the same question.



I typically run snappyHexMesh in parallel, and then reconstruct with the reconstructParMesh command. I also run reconstructPar afterwards and that should reconstruct the mesh fields. You can then open the mesh in paraview and visualize the cell levels as you would any other field value such as p, U, etc.



Below is typically what I run when creating a mesh. I hope this helps!

mpiexec_mpt -n 1 surfaceFeatureExtract |tee surface.out
mpiexec_mpt -n 1 blockMesh |tee blockMesh.out
mpiexec_mpt -n 1 decomposePar -force |tee decomposePar.out
mpiexec_mpt -n 36 snappyHexMesh -parallel |tee shm.out
mpiexec_mpt -n 1 reconstructParMesh -constant -fullMatch |tee reconstructParMesh.out
mpiexec_mpt -n 1 reconstructPar -constant |tee reconstructPar.out
mpiexec_mpt -n 1 checkMesh |tee checkMesh.out

To visualize the refinement levels of a mesh in ParaView, you can use the "Cell Data to Point Data" filter along with the "Glyph" filter.
