Hello all,
Greetings. I have been trying to model flow domain having slope at downstream in which the influence of VGs on flow separation would be investigated. I have used ansys workbench spaceClaim feature to create the flow domain with VGs which are attached here. I have founds few tutorials but confused. Some tutorials subtract VG geometry from domain and remove the geometry (fig.22) and in few tutorials after subtracting the VG geometry they kept the VG geometry (fig.23). I have tried both. But which one is actually correct or good for proper result? In the 2nd case i.e. domain with separate VG geometry, after meshing by ansys, inflation layers squeegeed near VG area. What to do?

Thanks in advance.
