3D Boundary Layer Laminar and Turbulent meshing
Hi all

I'm working on a flow around a car with both a laminar and a turbulent boundary layer. I did some wind tunnel tests to get to know where transition is and now I'm making the mesh, using Gambit, for the CFD computations.

For the CFD computations I will model the laminar boundary layer as a laminar zone in Fluent. I was wondering if I had to make a separate volume, containing only the laminar boundary layer? Because Gambit can only make zones from volumes.

Or is there an other way or program (ICEM or T-grid) which can convert the boundary layers, both laminar and turbulent, made in Gambit into zones?

For the laminar zone, you have to isolate this volume from the others.
If you create a BL, then you won't be able to set this region as laminar.
So you need (as you said) to make a separate volume.Then go to Zone panel (the one near the BC panel).
Then choose the volume and set it as zone. That's it from the gambit's side
