Hi Guys,

Can anyone tell me if it is possible to view how the mesh is partitioned after using decomposePar? I am using the scotch function.

I know that the points and neighbor patch info are divided into their respective processor files. Is it possible to visualize the decomposition?

Kind regards,
Conor

yes,
after decomposing, open your .foam-file with paraview.
for case type, under properties, select: decomposed case.

you should be able to see boundaries in your internal mesh.

Right, then you can either reduce the opacity a little bit or just show the geometry as "wireframe".

You can use processorField function object to visually check how your mesh is decomposed.

I think the following link is more appropriate for a user guide: https://www.openfoam.com/documentati...ssorField.html (the above is the API guide).

PS: By the way, I am one your followers who were trying to promote your page (can find your surname below) .

decomposePar -cellDist -dry-run
if my memory serves me.
Should be fast, since it only writes the cell distribution (as a serial field) but doesn't write the processor files.
