Connecting two cylindrical shells (pipes)

Please login with a confirmed email address before reporting spam

Hi all.

I need to create a geometry that is essentially a T-shaped pipe joint. How do I do that in COMSOL, without having to resort to external CAD tools? I tried to intersect two cylinders but couldn't get rid of the faces that block flow through the joint. BTW, I do not have the Plumbing Module :)

Thanks,
-Tudor

Hi

in the geoemtry section you can add, unite or convert geoemtric objects, and then you can select to keep or exclude internal boundaries. Try to not to keep the internal boundaries and you should then end up with a clean T pipe. But anyhow, some internal boundaries mostly have no influence on the meshing, nor on the result

Good luck

Thank you for the prompt reply. As it often happens, as soon as I posted this issue, I figured out how to delete the unwanted surfaces.

Thank you again.
