Hi
My problem is flow through a pipe surrounded by a rectangular block. Now I want to solve 3-D continuity, momentum and energy equations. Now, those equations need to be solved in cylindrical coordinate system for pipe and only energy equation need to be solved in Cartesian coordinate system for rectangular block.
Once open comsol model builder window after selecting the 3-D option, by default it is showing (x ,y, z) coordinate, that's fine when I am solving energy equation for rectangular block. But, (x, y, z) coordinate system can not be used for solving cylindrical system.
how can I resolve the issue?
