[ICEM] Blocking topo for hexagonal tube with holes

siw · February 9, 2012, 10:44

Hi,

Any ideas for blocking this hexagonal tube with an orifice in it? I'm using a hexagonal section as it makes a nice geometrical symmetry for the 6 surrounding holes and corresponding fluid symmetry boundary conditions along the tube length. The green surface around the hole is to be no-slip walls. and it's also showing the outflow surface.

This might be straight-foward for some but my DNA lacks PSYMN's blocking gene so I can never "see" blocking topos.

Thanks

I would first create a block for the whole tube.
Then cut it in the middle to capture the hexagonal section.
Then create O-grid.
Then cut again to capture the small orifices.

Could you post your geometry here so I could have a quick look ?

I would second the comments of BrolY and would like to add this: create six Y-blocks for six opening (orifices) at the periphery of hexagonal section and full o-grid in center for circular section.
