Paraview 3.98.0 does not update list of mesh regions
Dear Foamers,

since my upgrade from Paraview 3.14.1 to 3.98.0, a useful Paraview feature seems to be missing. Paraview 3.98.0 does not update the list of mesh regions any more. I define "update" in a sense that if a later time step has more mesh regions than the initial time step "0", the new regions should be added to the list of mesh regions. Paraview 3.14.1 does this as expected, while 3.98.0 does not.

This feature is relevant for me because I am importing geometry with snappyHexMesh. The imported geometry does not yet shop up at the initial time step "0".

My LES workflow is a bit special because I have a modified piso solver with y as vertical axis, but my Blender-generated STL input data have z as vertical axis, and because I execute both snappyHexMesh and the modified solver in parallel:

blockMesh > blockMesh.log 2>&1
decomposePar -force > decomposePar1.log 2>&1
foamJob -parallel snappyHexMesh
foamJob -parallel checkMesh -latestTime
reconstructParMesh -latestTime -mergeTol 1e-06
transformPoints -yawPitchRoll "(0 0 -90)"
transformPoints -translate "(0 0 6)"
cp -p 0/* 0.02
setFields -latestTime
decomposePar -force > decomposePar2.log 2>&1
foamJob -parallel pisoMod
decomposePar -constant

Although Paraview 3.98.0 correctly recognizes the updated internal mesh based on the contents of the processor*/0.02/polyMesh subdirectories, the imported geometry is not added to the list.

Has anybody else observed this behaviour? Do you have a suggestion how to solve or avoid this problem? Looking forward to receive your feed-back.

Best regards,

Greetings Marcus,

Which file reader are you using? The internal reader in ParaView or OpenFOAM's own plugin reader for ParaView?

Best regards,

Dear Bruno,

I am not using paraFoam, which would generate a temporary .OpenFOAM stub file but would not offer the "case type" choice "decomposed case".

Instead, following the thread decomposed case reader in Paraview,I generate a .foam stub file and open it with paraview, or paraFoam -builtin. So it is the built-in reader which I am using. This reader offers to read decomposed data directly.

My Paraview version is ParaView-3.14.1-Win64-x86.

Best regards,

Hi Marcus,

Have you tried Takuya's up-to-date plug-in? You can get it for Windows from here:

Best regards,

Hi Bruno,

very good suggestion. I have just installed Takuya's plug-in, and it solves my problem. It even offers a convenient way to rescan the timesteps.

Thank you very much!
