Hi there
I am using gridgen to make structured mesh for a 3d hydrofoil. my goal is to solve the problem for a incoming flow using a in house solver. The input mesh file for the solver is in star-cd format which is available in the gridgen.

my problem is the orientation of the 3D structured grid that im generation is not following any pattern. so it has become impossible for me to control the boundary condition in the solver. I could not find a pattern in the grid topology.

i need to know how can i fix the orientation of the cell in gridgen or how i can make structured grid so that the orientation is same for all my cells.
