Hello Everybody,

Briefly before Christmas I have a CFD Problem...
Maybe anybode can help me:

I am doing a transient simulation with cavitation. First I have made a transient simulation with cavitation turned off as initial guess. Now I have turned on cavitation and the solver explodes after a few Iterations. I get pressure values of about 300 bar, which causes my solver to abort.
See the Outfile Below:

Slave: 3
Slave: 3 Fatal bounds error detected
Slave: 3 ---------------------------
Slave: 3 Variable: Fluid 1.Density
Slave: 3 Locale : Innen
Parallel run: Received message from slave
-----------------------------------------
Slave partition : 3
Slave routine : ErrAction
Master location : RCVBUF,MSGTAG=1022
Message label : 001100279
Message follows below - :

+--------------------------------------------------------------------+

| Message: |

| An error has occurred in cfx5solve: |

End of solution stage.

| The following transient and backup files written by the ANSYS CFX |

+--------------------------------------------------------------------+
| The following user files have been saved in the directory |
| D:\kavitation_01_004: |

+--------------------------------------------------------------------+

This run of the ANSYS CFX Solver has finished.

Some Iterations before I got this Strange Notice:

Parallel run: Received message from slave
-----------------------------------------
Slave partition : 3
Slave routine : EX_TABLE
Master location : End of Continuity Loop
Message label : 009100008
Message follows below - :
+--------------------------------------------------------------------+
| ****** Notice ****** |
| While evaluating Fluid 1.Temperature, |
| Absolute Pressure |
| went outside of its upper limit. Its maximum value was |
| 3.5814E+07. The bounds error was handled by extrapolation. |
| If this situation persists, consider increasing the table range. |
+--------------------------------------------------------------------+

Some Details for my Case:

- reference pressure: 0 atm
- timestep: 5.5e-5 s
- inlet: total pressure
- outlet1: opening
- outlet2: pressure outlet


Any Hints appreciated! Thanks in advance

Simon
