Hello, how are you doing?
I´m facing a problem and would like to ask you if you have some hints about how to solve it. Recently i did a Comsol tutorial for a pipe flow simulation. In this tutorial it was used 2D axysimetric to build the pipe model. It was done building a rectangle and then they extrude it rotating that rectangle to form a cylindrical pipe. So they only build the mesh for the rectangle and solved the problem based on this mesh.
So my question is, there is a way to do something similar with rectangle cross section pipes? If it´s possible, can someone tell me how can i do this?
Thank you very much in advance

Dear Houari.
I suggest you look into the tutorial below
www.br.comsol.com/model/thermal-decomposition-2164
if you wish to simulate it as 2D.
If you wish to simulate it as 3D, you can use symmetry as described in the tutorial below
www.br.comsol.com/model/porous-reactor-with-injection-needle-25
However, if the flow in your pipe can be considered as fully developed, you may use the Pipe Flow Module to simulate it, as described in the tutorial below.

Hope that helps.
