[ANSYS Meshing] Interface node number and memory allocation problem

Whitebear · June 22, 2016, 02:22

Is there anyone who know memory allocation for interface node number? There are many long and thin pipe in the cylindrical tank. Hot gas flow in the pipe and water flows between tubes in the tank oppositely. So there are many interface between tube surface and tank. Is there any tip for setting memory allocation in CFX due to interface nodes number? I thought 128gigabyte memory was enough for any problem but I was wrong.

problem is not memory, but the aspect ratio at interface. size change between elements on both sides of interface should be less than 10

Thank you very much Far. I'll check it and try again. Where do you and can you check 'the aspect ratio at interface?' I can't find it. Mesh statics shows only overall aspect ratio only.
