elliptical solver - grid lines going into the surface

Hi,
I am trying to create my 3D volume grids. I am creating the domains that make up the block, specifically I am using the elliptical solver to get orthogonal/smooth grid lines. However, at sharp corners, the grid lines curve and go into the surface. I have attached screen shots of the grid. I have tried using Laplace as well as Thomas-Middlecoff functions for the interior control function. I have used both Multigrid and SSOR for the solution algorithm. I have tried both of the boundary control functions. The spacing off of the surface is 10x smaller than the smallest surface spacing. The angle control is orthogonal at the surface and "current grid" at the outer boundaries. The blending function for both the spacing and angle is "default exponential" but I have also tried linear blending function. I can't seem to figure it out. Anything that will fix this problem? thank you. -Paul |
