prism layer not extending till the end of wall

arun1994 · September 5, 2019, 07:26

I have a film cooling problem with a cylinder at an angle. When I try to use prism layers for the cylindrical wall, the prism layer tends to shrink towards the inlet. I have never experienced this before and I tried changing parameters one by one without success. Any suggestions?

This happens always due to the algorithm used.

You can tinker with the layer reduction percentage, minimum thickness, as well as the angle limit (I can't remember if it is concave or convex for this scenario) to change how it looks superficially but you can't really avoid it.
