CFD-Post: Polyline Export at Integration Points
I am trying to write a clever script which will conveniently show me my boundary layer resolution among other things. So far, I have successfully been able to get polyline files containing normal lines to my surfaces. The issue I'm facing is that I only want data at the integration points.
Currently, I have to hand define how many points the polyline contains. CFX will then give me data at each point that I define. So, when I plot, I can "see" the integration points by where my line bends, but I have data points in between that looks linear interpolated.
From an ease of scripting/charting, I would like to, e.g. define my polyline by only two points. Then, have CFX give me interpolated data at all the faces it crosses.
I know this is. . .well quasi-possible, because Post does this when you do a polyline by boundary intersection. If you do this, you clearly get only the integration points in your polyline. Due to geometry, it's simply not possible to create my polylines in this manner.
If anyone else has another suggestion as to the best way to get this, I would greatly appreciate it.
If worse comes to worse, I can write a script to calculate the derivatives of my lines, and where the derivative changes, I will assume that is an integration point, and data reduce in that fashion, but I'd just rather not.
