Default meshing of a wing for lo speed flow
Posts: n/a
hi, i am working on the lo speed (mach 0.0403) cfd analysis of a wing which is of rectangular shape, has dihedral, and there r front and rear radius , i.e it is in b/w circle and rectangle.

the problem i have is that when i make the vol of the wing in gambit and subtract it from a big cube 2 make my domain, the resulting vol can be course meshed, but not with the fine msh. generally i get AN error

"initialization failed, perturb nodes and try again"

somtimes it also says that chk ur msh in area of small gaps

how can this prob b solved
