Hello everyone!

I'm meshing a human ascending aorta model with ICEM v14.5

I imported the CAD model in .stl format. I'm doing an hexaedral mesh.

Actually, everything works fine meshing the model, except for the bifurcation.

I tried many many different ways to figure it out, but the pre-mesh just doesn't work.

I uploaded some screenshots to better explain the problem I'm having.

In the first screenshot, there are the blocks I used to outline the shape of the model.

In the second screenshot, there is the very bad result of the pre-mesh bifurcation.

The last screenshot is an overview of the "pre-mesh" model.

Thanks for the help, it is very appreciated.

Have a nice day!
Rosario
