Hi guys,

I've had some experience working with ICEM but now I'm trying to generate a multizone mesh for ELES for a very simple flat plate (bluff body, perpendicular to flow). I'm wondering if anyone can give me a tip or two in terms of doing this with hexa structured mesh. I have split the blocks and added them into different material point parts (fluid-rans and fluid-les). However I'm having trouble with 1. having non-conformal mesh at the interfaces, since I don't want such high resolution mesh to extend out to the RANS zone, and 2. have two surfaces at the internal walls so that I can have corresponding interface BCs.

If there's something obviously wrong with my approach please let me know. I've done the ICEM tutorials and the geometry given somehow have two surfaces at the interface walls to assign them as interfaces, and also for example with the hybrid cylinder tutorial it uses non-structured mesh with hexa structured mesh and they are able to conform at the interface.

I guess as an extension I should ask, does having non-conformal mesh like this even make sense/good for the solver?
