Im trying to create an expression in Post to extract the boundary layer length () from my simulation at any point on the surface. I have a simulation of a turbine blade in a rotating reference frame.
So far what I've done has been to define a surface at some distance away from the blade surface to define as my freestream velocity. Following this I need to create an expression to extract the velocity at 99% of this value in the corresponding coordinate system and then to plot a surface of the heights above the surface corresponding to the 99% velocity. I've attached a plot showing some of my geometry. Any suggestions as to how to go about doing this? Im new to Post and CEL and I can only seem to do scalar expressions. |

This sounds challenging to do in CFD-Post. I would export your data and do it in matlab, python, tecplot or something like that.

Thanks for the suggestion! I was wondering if it was possible in Post but you've confirmed its not.
