Hope suggestion about how to generate the mesh for SU2

[zhang-qiang-github]

I want to implement CFD simulation with SU2.

A tube is used to simulate vessel, and it looks like:

I hope the wall should be red color part, and inlet/outlet should be yellow color part:

Then, tetrahedron is generated from this mesh.

My question is: how to build inlet/outlet/wall from the geneated tetrahedron? Suggestions is needed to generate the SU2 mesh. Any suggestion is appreciated~~~

What is your meshing tool? Usually, the inlet, outlet and wall are independent surface entities and you can select them, give them a name, and mark them as a boundary.

I will try gmsh to generate my su2 file. Many thanks for kindly reply~~~
