CFX unsteady flutter analysis

maheshchamarti · January 8, 2018, 17:31

Hi,
I am trying to do a flutter analysis of a single row flat plate case. I had no issues doing the steady simulation. when I do the unsteady simulation by prescribing blade motion the simulation is crashing due to reverse flow at inlet.this is my first time trying a translational periodicity condition at the periodic interfaces. please suggest a solution. i have attached a picture of the mesh. Thank you.

Showing an image of the velocity field which shows the reverse flow would help. Also please attach your output file.
