Hello everyone ,
I am new to the forum ; I am working on my thesis for mechanical engineering ( first level degree ) . I have a problem with the generation of the grid to ICEM ; it must be an unstructured mesh 3D . The problem is that there are lots of holes between two surfaces , the most important : they are a cylinder that is drilled to the base by two conical . It is difficult to explain both the geometry and the grid . I usually generate the mesh with method robust ( octree ) , and I havo to use smooth advancing front after that . My experience is limited, so I hope that someone will give me some advice . Thank you !
P.s. : is it possible to upload my icem file ?
