Mesh Error: Cannot Generate Basic Mesh

Jim Schmalzried Dec 13, 2010 2:10 PM

Hi All,

I just got a strange error in Flow Sim 2011. I created a new external flow simulation that is VERY simple (basically flow over a flat surface parallel to the flow) and I got an error when I rebuilt the simulation that read "Cannot generate the basic mesh. Please check the mesh settings."

Any clue as to what's happening here?

The Comp. Domain doesn't fully encapsulate the flat surface, just a portion of it. I tried verious settings of the initial mesh, but to no avail.

Thanks!

Jim

Hmm. Not sure the cause of the problem in the first place, but I did manage to eliminate the error.

In my case, I tweaked the mesh settings manually (specifying the number of cells in X, Y, Z) to get the mesh to work. Though, There didn't appear to be any specific number of cells that worked...as long as I typed in an even number, it seemed to be OK.

If anyone knows WHY this occurred in the first place, that would be good. It was the first time I have seen this error.
