So, here I have a convergent-divergent tube type, like a "venturi" and I want generate a structured mesh but I'm use academic package and I don't have ICEM CFD. I need a small height in the cells near wall, for this I try to use inflation layers but when I make this I get a unstructured mesh. If my domain were 2D I would use edges to imprint size controls, but as the domain is 3D I don't know how is the best/easy way to do this.
Someone have some tips about it?
Thanks for helping,
