Dear All,
is parallel processing available for mesh generation in openfoam for blockmesh?

Hi
As I know, nope.

  1. blockMesh cannot be executed in parallel.
  2. snappyHexMesh can be executed in parallel.
Here's an example thread about this: http://www.cfd-online.com/Forums/ope...ion-cells.html
It's been over a year and AFAIK it's still the same as usual.

You can make a coarse mesh in blockMesh, run decomposePar, then run refineMesh or refineHexMesh in parallel to bring it up to the desired resolution.

:rolleyes: You gave the summary answer to Dr Borse. I wanted for him to go search how it can be done, which is described in the thread I indicated before ;)
