Null domain Pointer error
 

Hi

I used gridgen to create the mesh and then exported the mesh as a case file .While reading this case file in Fluent, I got t the following error message
==============================================
arning: ST_Malloc: out of memory.malloc_storage: unable to malloc number of nodes, size 55680740, t 3, myid 1000000.
