Hi Everyone,
I create a combustor geometry with a vaporiser tube in ICEM. The tube has one open surface to allow for the injection.

I use tetra mesh type. It looks fine with the shell mesh but after the volume mesh is computed, the shell mesh disspear. The volume mesh goes through my tube surfaces (as shown in the picture). When I import the mesh into FLUENT, the whole vaporiser disppears.

Unless I close all tube shells which is not what I want, ICEM does not regconise my tube as surface and treates it as fluid. If anyone has any ideas on what may have gone wrong, give me some suggestions, please.

Thank you very much.
Jenny

BrolY will become famous soon enough
Define the tube vaporizer as an internal wall.

Hi BrolY and Far,
Thank you very much for your suggestions. I can now mesh the geometry successfully. And Far your youtube video is amazing and easy to follow. Thanks again!
