Hi everybody,

I am going to mesh a perforated three dimensional geometry as in attached figure. I would like to have mostly Hexa mesh conforming to geometry. Is it possible to use ICEMCFD for that? Do you have some general recommendations? The Geometry will sit on the bed or wall, and with an enclosure. I want extremely fine mesh surrounding the geomtry and in the wake of the geometry to capture vortices. Thank you.

You can generate hex mesh with ICEMCFD for this geometry. But it would be all manual process and would take a lot of time and effort. You can go with tet mesh instead which would be much faster. 

Please go through help manual for more details 

Regards,

Keyur

It looks like it has some symmetry. If you create a blocking pattern, you could then copy this around to create the full domain. One small advantage of this approach over the tet mesh is knowing your mesh is symmetric. When you look at vortices shed by the object, the question would arise (from an older prof.) how can you be sure that these are not tripped by the errors caused by the unequal grid.
