Hello everyone here,

The simulation I want to do is that, there are a bundle of wired hollow pins, and I want to know the velocity and pressure fields around one pin, and maybe thermal field around it later. And I build a hexagonal prism area by using ICEM CFD, the problem is that, when I rebuild the topology, the geometry is ruined. And I have changed the tolerance of build topology, it still doesn't work. If I do not rebuild topology, meshing fails.
Could anybody give me some suggestions on rebuilding topology or the simulation? Thanks.
