Hello,

I am working with pulsatile flow in a flexible tube model.Designed the tube in ansys workbench and gave the material properties.geometry of the fluid nd mesh is done in Ansys ICEM CFD.when tried to solve the combined in ANsys solver the following error popped up.

Added /FLOW?SOLVER CONTROL/EQUATION CLASS:momentum/TRANSIENT SCHEME/TIMESTEP INITIALISATIONS/Option=Automatic

Processing ANSYS Input File(Running CCL2MF)

Created C:\Documents and Settings\Divya\straight pipe\geoagdb_002.ansys\ANSYS.mf

Starting ANSYS Solver

An error has occurred in cfx5solve: ANSYS Solver terminated unexpectedly with return code 3840

This run of the ANSYS CFX solver has finished.

Could you please say what is the problem.

Check the ANSYS log files located at geoagdb_002.ansys\. They might give you some answers.

Please tell me what is the problem..

I am doing FSI using ansys workbench.

Take a look at the ANSYS log file. The CFX out file just say ANSYS died.

Hi stumpy, some how the previous problem got solved but now i have a new error could you please tell me whats wrong..

Same as before - check the ANSYS log file since CFX could not get a mesh displacement from ANSYS (i.e. ANSYS died)

sulakshanarya · February 24, 2012, 04:44

No i didn't find anything saying ansys died, or trouble in transferring mesh from ansys... Is there anything else causing the problem???

The error you posted showed that ANSYS failed:

ERROR -- CFX encountered the error: Read. Fatal error occurred when requesting Total Mesh Displacement for Interface.

If CFX cannot read the displacement, which comes from ANSYS, then it's more than likely that ANSYS failed. You need to look in the ANSYS.stdout file to find out why.

Hello everybody
I am doing FSI problem
but as soon as I press solve the ansys says:

ANSYS Solver terminated unexpectedly with return code 1280

anybody can help me?
