Model design from 2D axysimetric

Please login with a confirmed email address before reporting spam

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

Houari

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

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.
