Hi everybody

I simulated a blood vessel in ansys.My simulation is a fsi case with pulsatile blood.vessel is elastic and i fixed inlet and outlet of blood vessel.

I have simulated blood as a non-newtonian fluid.but after some steps I get this error:

ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |
| CFX encountered the error: Read. Fatal error occurred when reque- |
| sting Total Mesh Displacement for Wall.

ERROR #001100279 has occurred in subroutine ErrAction. ] |
| Message: |
| cplg_SendCommand failed to send the command: ERROR -- CFX encount- |
| ered the error: Read. Fatal error occurred when requesting Total |
| Mesh Displacement for Wall

Do anybody know about this error?and how to fix it.
what condition should I place for vessels's outer surface?
