FSI - compressor blade vibration
 
Dear All,

I'm trying to set up a one-way FSI analysis for a compressor blade. The flow field is to be modelled around an oscillating blade. I used WB mechanical to solve the vibration modes. It would be necessary to impose a sinusoidal oscillation of a particular vibration mode of interest and then solve the transient flow field.

The problem is I don't know how to transfer the modal displacement data into CFX. I was thinking of creating an expression for an input to Specified Mesh Displacement, however I am looking for ideas on how to program this in CFX. I am using WB for the process.

Any help would be highly appreciated.
