Hello,
I've problems with the prism layers when it takes a 90 deg turn or at perpendicular surfaces as seen in the picture. Could anyone let me know which value controls the snapping funtion that I get smooth prism layers without collapsing. Looking forward to your replies. Thanks!
Cheers,
J

Hi Jhony

I must say that you will have to fiddle with the layer reduction percentage, prism to core aspect ratio values and prism layer aspect ratio. Also try to manipulate the poly growth rate. Increase the quality threshold of polyhedral ratio and increase the optimization cycles for good quality cells.

you will find the range of values for all the parameters i mentioned above in the help manual.

Hope this was helpful
