problems creating a mesh of inlet pipe
 

Hey,

it's actually a quite simple question, but I'm a newbie to ICEM. I have an inlet pipe which enters a cubical structure. Therefore, I don't have a surface at side where the water is entering the cubus. When I create the O-grid, the mesh at the side without surface is just completely messed up. Hmmm, how can I create a hexa-mesh at the pipe outlet (where the water is entering the cubus)?

Thanks
Peter
