ansys solver terminated with returne code -1
 

Hello sir,
My work is related to fluid -structure interaction. for that i am using static-structural and Cfx for solid and fluid parts respectively.
Simulation goes on and meanwhile it shows error and stops. The Error is as follows:

This run of the ANSYS CFX Solver has finished.
Please reply sir, what can be possible problem and how to remove the problm.
Thank you.

You need to provide the ANSYS.err file since ANSYS is crashing not CFX.
Check the displacement at the interface via Monitorpoints in CFX.
Check the mapping of the InterfaceInterpolation--> should succeed for ALL points on the Interface.
Get rid of every warning in the Ansys.err.
