HI!!

i have a problem with the solver cfx. when i am running a simulation, it stops and appears this
================================================== ====================
OUTER LOOP ITERATION = 43 ( 12) CPU SECONDS = 6.268E+03 (2.567E+03)
----------------------------------------------------------------------
| Equation | Rate | RMS Res | Max Res | Linear Solution |
+----------------------+------+---------+---------+------------------+
+--------------------------------------------------------------------+
| An error has occurred in cfx5solve: |
| |
| The ANSYS CFX solver exited with return code 1. No results file |
| has been created.

Can anyone help me??

Regards!!!!!

First of all, post a bit more information.

This error basically doesn't tell you anything.

Did your simulation diverge?
Check the "Rate" of the previous iterations. It should be lower than 1 (can be a little over 1 and its not a problem), if its significantly bigger than 1, it's diverging fast.

Did the linear solver fail?
Check whether there is OK, ok, F or * in "Linear Solution"
if F or *, that's most likely your culprit.

But give more information. Static or transient? Is it a iteration where a load is applied? Mesh movement?

HEllo!

The simulation is a steady-state calculation of a multiphase-flow ejector without mesh movement.

When the simulation ends with errors, both the numerical solution and the rate are good. The numerical solution is "OK" and the rate is less than one. But the solver stop and return with the code 1, i don't know this error.

What do you think??

THANK YOU VERY MUCH

what about your mesh quality? expansion factors etc?

HELLO...!!!!

I have the similar problem....

So, what did you do to fix that?

Many thanks............!!!!!

Hi friends,

I'm simulating a simple tube in 2-phase, using Droplets.
I've experienced the same problem.

Can a friend help me?

Thanks
