Hello everybody.

I'm running a steady state simulation about a multiphase flow (air and water).
On CFX - Solver I got this error after 16th iteration:

Parallel run: Received message from slave
-----------------------------------------
Slave partition : 3
Slave routine : ErrAction
Master location : RCVBUF,MSGTAG=1214
Message label : 001100279

Do you know which could be my mistake? please help me for this...

Thanks in advannce...

I, too, have faced that problem several times. Though i am but a beginner i' ll attempt to provide a few pointers. Common causes for that said error is a bad grid, a poorly structured physical problem (irrational boundary conditions) or simply a matter of numerical precision (some problems simply need double precision, tighter convergence criterion or smaller time steps). For instance, at some point i kept getting overflow error at the very first iteration, which led me to believe that it had something to do a parameter or an initial condition. Removing/optimizing a boundary condition solved it. These matters, at least for me , are quite complex and i personally approach them by process of elimination. Also, grid is extremely important and in some cases you should avoid generating a grid automatically. Lastly, you should always check cfx-solver's diagrams to see if and how well your system is converging.

if it says slave process failed, sometimes its more happy, when you dont run parallel processes/cores. Just switch to single. Helped me a few times.
