Hi, guys,
I am doing trasient simulation of a rotating blade. I want to monitor pressure at some location of the blade outlet, the location is statonary in the absolute coordinate and do not rotate during the simulation.
As I know, CFX will assign a vertex according to the specificed monitor location, and the vertex will rotate during the simulatioin. That is not the way I want to monitor. Is there any solution?

Thanks!

If you are done with the simulation and working in post, define the vertex in post. and extract its value for all time steps. When you do it in such a way it won't rotate in post.

Thanks for your reply!
I want to perform FFT analysis, so I cant save all the trasient results on my harddisk. It is too large!
Is there any way to extract the vertex value during the CFX solving process?

define it in pre and get data on that point only

I tried "probe(Pressure)@" expression, however, the probe location must be a monitor point or source point according to CFX manual, which will rotate during the simlation.
Also, I tried to define "export results" in CFX pre, but only a surface can be exported, not a point!
Would you please tell me more specificly how to define the point?
Thank you!
