Dear all,

First of all thanks for reading my thread.

I have a qusetion concerning the O-grid generation.

As is shown in the pictures. When i want to construct a o-grid on a face between two blocking, some very small cubes will be produced on the blue edges and making the edges active.

If i tick pre-mesh, the blue edge will associate the geometry curves automatically.

It would be really nice, if somebody could help me!
Thanks in advance,

Sun

-> If you want to use the shape of the geometry in edges use it every where including internal and surface edges and curve edges. I see that you have used spline edge (or linear splits) for the internal (blue) edges. but not on the outer green edges. This might cause negative elements.


-> rescale the ogrid such that they are equal everywhere. (there is an option to rescale o grids)

-> go to assosciate (faces to parts) and assosciate all the faces on the surface to the surface part representing it
