Rotating plane in CFD-Post

davidwilcox · November 8, 2016, 03:09

Hi,
I am currently doing some post-processing of a rotating blade in CFD-Post. I am interested in looking at the pressure distribution along a polyline ( i created this using the intersection method between a plane and the surface of the blade). For a stationary case, this is fine. But I have a transient case where the blade is constantly rotating. Is there a way in CFD-Post to make the polyline rotate with every timestep?
Many thanks in advance.

Cheers

Hi,

Your poly line is generated using the intersection method between a plane and the surface of the blade, so it rotates with the blade.
one way is that, export the coordinates of the poly line and again import those to CFX post and define a new poly line. it just came to my mind I am not sure if it helps.

(can be tried)
