The following video shows the procedure of meshing fluid domain around wind blade using Fluent Meshing.
We have had some issues when creating the volume mesh. We sometimes get an error that says "Please fix the overlaps along multiconnections..." This often occurs in the setup of periodic boundary conditions, where remeshing can create issues with the sharp trailing edge of the blade. Use clipping planes to verify that this is the source of the problem, and then edit the periodic boundary condition setup. Change "Remesh Asymmetric Mesh Boundaries" from "auto" to "no," verify that the trailing edge is unaffected by the remeshing, and then continue.
