Hi,
I am working on vortex tube by taking 60 degree sector of vortex tube. I am using gambit to make geometry and meshing.
The way i made -
1 Create a geometry
2. then link the faces
3. the make nodes on all edges
4. mesh all faces
5. mesh all volume
6. define boundary condition
But the problem is that whenever import in fluent and check for mesh it shows a periodic angle of 2-3 degree instead of 59-60 degree.
please help me how to link the faces correctly and make a correct mesh.
