hello all;

I'm trying to mesh a cylindrical pipe which is 20 cm long, 2 cm in diamter (its axis is in x direction) and at the middle of the pipe, there are two branches, on in y direction and the other in z irection, i.e., the brances and the tube are perpendicular to each other.
I need help to creat the mesh.

Thank you.

What tools are you using? What problems are you running into? Most importantly, how do you expect to get any help asking a question like this, with almost no information?

Are you trying to mesh the inside of the pipe or the outside?

hello;
im using GAMBIT. There is flow coming from one branch and it distributes to the main tube and the other branches. How can I split these volumes to create cooper or any other high quality mesh?

I still consider my self a beginner with Gambit/ Fluent. What I have been doing meshing the surface with a tri-pave mesh. I do my best to ensure it has a great skewness score. Also on the inlet and outlet. With that, I hope when I generate a volume mesh, maintain good quality. Tri/tet mesh where meant to tackle difficult contour like pipeline branch off and splits.

Try it. I hope this helps.

Tutorial 1 of Gambit should give you some ideas of doing this. Basically you need to split the whole domain at connection location, which results in three volumes. And each volume should share two faces. Meshing the shared faces first and then you will get hex mesh for all three volumes
