[ICEM] ICEM CFD meshing for a complex geometry

djchilli · November 20, 2013, 06:29

Hello everyone,

I'm a complete beginner in ICEM CFD and I would like some help. I have basically created a heat exchanger model in SolidWorks which I then imported to ICEM CFD to mesh. There are basically 21 rectangular channels which I successfully meshed. I have left triangular gaps in between the channels as you can see in the image, which I plan to mesh later. I have also meshed the outer boundary which is basically like a disk.

I'm finding it difficult to mesh the outlet and inlet basically. I modeled the outlet just like the 3d pipe junction in the tutorial so I could learn from the example, but it's not meshing it right, I think its because of the interface.

The inlet is basically a cylinder, but Im unable to mesh it properly too, possibly because of the interface at the other end of the inlet.

I would appreciate guidance on how to go about this, because I'm a complete beginner and I've been trying this for weeks without any results.

Thanks in advance

You need to setup the blocks for each part of the junction then create an o-grid on the faces which represent circles.
