Changing Mesh Velocity
 
Hi,

Does anybody know if in an FSI simulation I can POKE the mesh velocity before the calculation begins.

I have a JB that changes the co-ordinates but CFX calculates the mesh velocity. I would like to give it a mesh velocity without changing the co-ordinates.

I tried to add a JB before the linear solver and tried to POKE 'MESHVEL' located under /LATEST/VERTICES/ in the MMS directory. But I feel the linear solver matrix has already been constructed and this has no effect on the solution.

The main reason for doing this is to incorporate effects of grid motion without grid distortion.

Any pointers would be helpful. Anil
