amsys is on a distinguished road
I am doing a fluid-structure interaction simulation by coupling ANSYS CFX with ANSYS mechanical. When solving for a solution the run terminates with the following error message:



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

End of solution stage.

+--------------------------------------------------------------------+
| An error has occurred in cfx5solve: |
| |
| ANSYS Solver terminated with return code 3840





The error in the ANSYS.err file is as follows:




/COM,ANSYS RELEASE Release 16.2 BUILD 16.2 UP20150629 10:46:20

*** WARNING *** CP = 4.555 TIME= 10:46:26
The /BATCH command must be the first line of input. The /BATCH command
is ignored.

*** FATAL *** CP = 5.647 TIME= 10:56:26
Could not connect slave socket from master process in coupled
simulation. Error message: Time out.

************************************************** **********************
The above error is non-recoverable by ANSYS
ANSYS run terminated by the indicated error
Current data base saved if possible.
************************************************** **********************

Any suggestions on why these errors are occurring would be great.

Thanks.
