Dear all,
does anybody know, whether it’s possible to create a boundary layer at the inner wall of a geometry, if I am not using the Cooper scheme to create my volume mesh? My problem is: I want to mesh the geometry of a vessel having a bifurcation. At this I want to create a boundary layer of hexahedral elements, because I need a good spatial resolution close to the wall. Afterwards I would like to fill up the rest of the geometry with tetrahedral or unstructured hexahedral elements. Unfortunately gambit refuses to mesh the surface via “Quad Map” or “Quad Submap” and due to the bifurcation I cannot use the Cooper scheme. Does anybody have an idea how I can get such a hexahedral boundary layer by using Gambit or Tgrid?
Thanks a million,
Lilly
