Mesh Size Limit
 
Dear foamers:
Can someone tells me if there is a size limitation to the mesh using blockMesh? If I want to generate a mesh with billions of cells, how could I do, since Openfoam seems to kill the process of blockMesh when the mesh size is too large? How to solve the problem or where is the error coming from?
Thanks a lot.

Dear Dirk,
without your blockMeshDict and the error log an answer is hard to give.
Just post it in

Code:
code format
and we have a look at it.

Best regards
Julian

Please check your hardware first. Is your machine where you run blockMesh equipped with enough available RAM?
