Different boundary layer thickness
 

Dear all,

I'm trying to model different boundary layer distributions in my domain and I need some help.

I define different total heights for each part where I want a B.L. with 1 single layer. No problem.
Then, when I try to split these prisms into several ones with the correct expansion law and I specify in which parts I want that particular type of B.L .,ICEM makes this distribution for all the different parts even if they are not selected in the split menu.:confused::confused:
If then, I'll try to produce another B.L in another part, it resplit all the prisms again.
Any idea how to produce different BL distribution in adjacent parts?
Thanks
