Volume Mesh in Prism Layer-Any ideas why?
 

Hello everybody,

I am currently facing a problem which is confusing me a lot.
I created a volume mesh but realized, that StarCCM also put volume mesh cells in my prism layer.
See a picture below:

Does anyone of you have'n idea how that could happen?

Thanks in advance,

Rene

I think that your prism layer is too thick.
Prism layers are generated near the wall to solve near wall functions.

There is a method to calculate the prism layer thickness using geometric progression.

a=Y+ value
r=layer growth

Why not try to reduce the thickness first and increase the number of layers instead?

just my 2 cents.

Depends on Star version; 8.04 happened to have errors in meshing (some primitive geometry case) that 8.06 doesn't.
