floating point error when starting to iterate
 
Hi!

I know, there is a lot of discussion about the floating point error, and there are a lot of answers.

But, I can not find a sollution to my problem:

I have a 3D geometry with about 1.000.000 cells. It is incompressible, air. I tried all solvers, but every time the same: The floating point error comes when I am starting to iterate. Not even the first iteration can be done...

I tryed different urf, different courant numbers and different discretisation...

Any idea??

Ralf

It might be due to your low computer memory(RAM). Try to reduce the grid about 500000 cells and see does it works or not.
