@@mmnyako yeah, you are correct 👍

@@aerotech84 thank you!

this is a 2D simulation of the overtaking process

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.

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

thank you!

I combined sliding mesh and layering dynamic mesh

@@aerotech84 like how did you make the boundary slide? Mine just shears the boundary and gives negative volume.

​@@qumit165 about sliding mesh you can check this playlist of mine: ruclips.net/video/qRBKqwk2P6k/видео.html if you need details help con can contact me through Instagram: @dongaero

Yeah but how do you make the sliding + dynamic together to work? I understand there is some layering involved, but how did you slide your block so that mesh generates behind it? Also do you think would it move with 6 DOF?

@@qumit165 I set mesh motion for the moving mesh, I used the layering method to create re-meshing front and behind it. I use udf with CG_MOTION, I do not use 6DOF.

Ansys Fluent supports both sliding mesh and dynamics mesh. They are two different techniques. In this video, I applied both of them to simulate the moving mesh.

@@aerotech84 Thanks :)

sure, thanks

Here, the macro is used, and it is active in only 1 Fluent Case, then you can not name it automatically for different Fluent Cases.

Noted, thanks for the reply
