[ICEM] ICEM automatically merging two separte parts

kazra · May 9, 2016, 08:48

hi all
I have a model of an air to air heat exchanger. basically there are two air streams which are separated by a copper foil of 0.01mm thickness. when I mesh the geometry in ICEM the software automatically considers the copper foil to be part of the cold air stream. so because of this problem when I import the mesh into CFX it is not possible to specify boundaries for the copper sheet. any suggestion would be appreciated.
thanks in advance

in CFX you can set the boundary as thin material, then select copper and thickness. No idea, if that works in ICEM. Plus you would have to make 2 domains. And I found (in CFX), you have to set an expert parameter, so its 2 different physics, otherwise both fluids would mix.
Found that is an heat exchanger, there are 2 different fluids I dont want to mix.
Again, thats in CFX, not ICEM, but you may find something there. Separating domains was in Beta options.
