unexpected elements shape in fluid domain meshing for Fluent
Hi, I am trying to create structured mesh in Workbench meshing using multizone method for a flow domain around 3D finite swept back wing. Mesh is generated successfully without any error, but I am getting unexpected element shape near the trailing edge. If I reduce element thickness near the surface of the wing by inflation or by very high biasing to get desired Y+ value, it results negative cell volume. If someone can tell me the reason for this and how can I overcome this problem it will be very helpful.
