grid for wigley hull any suggestions?
 
i am analysing incompressible free surface flow around ship hull. ship hull is assumed to be parabolic at each section (this is called wigley hull). what type of grid can be used. i will be using SIMPLE algo to solve. any ideas?

Hi,

For ship hulls a HEX mesh is best due to the aspect ratio of the overall shape.

I have made a quite a few hulls for ships and boats with HEX meshes as the number of cells compared to a TET mesh can be orders of magnitude lower.

Cheers
