I was away traveling, so please excuse my late reply.&nbsp;&lt;\/p&gt;&lt;p&gt;Before I try to make a more refined mesh, I wonder if you think a polyhedral or a poly-hexcore created using fluent meshing should be sufficient for the simulation, or if I should try to improve the hex mesh I created using ICEM?&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;I think the bulk flow is behaving as expected.
