@aerotech84 One more question pls, why did we separate the boundary layer in the first place 2:11 ? my guess is that we don't want to apply dynamic mesh remeshing, layering and smoothing on the boundary layer zone, but only apply the remeshing on the tetrahedral/triangular cells of the fluid zone pls correct me if I am wrong Thanks!
I am confused, multiple zones created when you separate the boundary layer. what is domain:011, interior-domain:003, interior-domain:010, what are these new domains ?
A computational domain normally has 2 kind of domains: domain (includes all interior, wall, inlet, outlet type; you do not see it on boundary conditions) and interior-domain (only interior type). The fluent will auto name the separated domain. In this case interior-domain:010 is the boundary layer domain, interior-domain:003 is the domain connect interior-domain:010 (boundary layer) with domain (main domain); domain:011 includes interior-domain:003, interior-domain:010 and move-car wall type, you can not see it in boundary condition section.
@@aerotech84 One more question pls, why did we separate the boudary layer in the first place? my guess is that we don't want to apply remeshing and smoothing on the baoundary layer, but only apply the remeshing on the tetrahedral/triangular cells of the fluid zone pls correct me if I am wrong Thanks!

@@mmnyako yeah, you are correct 👍
@@aerotech84 thank you!
How to get the value of cell height?
ANSYS has a function to scan your domain. You also can see this information when you create the grid mesh or double-check by using the ANSYS ruler.

@@mmnyako you are right, remeshing method may reduce the mesh quality, also remeshing only available with triangular mesh in 2D now.
