Hi every body,

I try to simulate a flow through a pipe with a 0.5 bar gauge pressure inlet and 0.5 m/s velocity outlet.

I attached the geometry, sorry it's in french, "eau" means water.

I think it is impossible to do that on Fluent, that is why I am trying to do it on CFX but I usually don't use it...

I need to keep the velocity outlet constant and change de pressure inlet to observe the changes on the interface water/air level.

And when I try to compute, I have :

--------------------------------------------------------------------
ERROR #004100018 has occured in subroutine FINMES.
message :
Fatal overflow in linear solver.

-------------------------------------------------------

An error has occured in cfx5solve :
The ANSYS CFX solver exited with return code 1. No results file has been created.


Could somebody help me ?
