cudn't allocate fine level coeffi matrix in fluent

February 5, 2007, 06:33

I am solving a problem which has 4548960 cells 5297508 vertices. Fluent gives me error"couldn't allocate fine level coefficient matrix" without starting. What can be misatke? pls can anybody tell me. I think that it may be due to space problem or memory problem. The machine has 4 GB RAM.

Thanking you.

yes it is due to memory problem, even though it has 4gb, the fluent process is not allowed to allocate more than 2 gb.

There was a discussion on this issue , do some forum search.
