Hi everybody,

I want to generate a 3d mesh for a geometry which is not a quite good shape to generate structured mesh but I devided the model to the little bricks and It can be meshed as structured now. But the problem is that, for example, on the fins, I have to use unstructured mesh on the tips and bottom side and combine this to the adjacent bricks (which are structured, the surfaces have quad mesh). At the same time, I use boundary layer mesh and there occurs thin and tall elements on the surfaces so those are not convenient for unstructured mesh.

Qstn 1: Is there a way to mesh these regions like hanging nodes? If yes, how?
2: Is there any other way to generate a 3d mesh like this?

thanks
