Hallo everyone,

When I'm doing the 2D Model I meet some problems.And I think the Problem has relationship with the mesh in ICEM

I'm making a model of cooling system of a power transformator and there exists isolator (red part) between ducts in transformator. Please have a look in the first picture(Structure). My problem is that, the Interfaces of every part should be chosen separately. For example the part Isolator, the top side and the botton side should be defined as solid fluid interface because they have connection with cooling oil and the right side and left side should be defined as solid solid interface because they attached with ducts. The second and third pictures show the right answer of the interfaces. But in my model, I can't choose these 2D primitive part separatly. In the Region List, I only have a 2D primitive with whole sides like a rectangle. Please have a look in the last picture. So I think whether there are something wrong with the mesh in ICEM or another possibilities. So I hope you can give me some suggestions to let me solve the problems.

I'm very very appereciate for your help!!!!!
