How to determine boundary layer thickness in Direct Mesh ?

Andi_Didi · November 6, 2017, 19:41

Hello everybody. I have questions.
I'm starting to learn how to make simulation with Star CCM+. And i am glad, i have manage to mesh the domain of my case as i show you in pictures below.

But as i go with direct mesh operations i can't manage how to make a boundary layer mesh. I have using Gambit 2.4.6 before and i always use boundary layer mesh to determine the distance of first cell to the wall, and its boundary layer thickness.

So how do i make this meshing ?

at near wall i have hexahedral mesh and i can set the thickness. But in the middle area i have polyhedral mesh.

I've tried to search the tutorial and etc. but i can't find the way.
Can anybody help me? Could you show me some links to the tutorial ?

Thanks for your help. I really appreciate it.
