The meshing process is:
1. Create virtual topology to merge surfaces in order to simplify the geometry.
2. Create named selections (inlet, outlet1, outlet2, wall_artery and fluid_zone).
3. Add constraints to the automatic mesh (inflation mesh and body sizing).
4. Preview automatically generated inflation mesh and finally, generate volume mesh.
The videos below show you how to create the mesh for the fluid domain.

Comparison of surface mesh generated with/without using virtual topology
Mesh generated without using virtual topology. There are more dense cell locations on the surface where the faces come together.
Mesh generated after using virtual topology as shown in the video above. There are less dense cell locations on the surface. The remaining cell-dense regions can be fixed by setting minimum cell size as shown in the third video below.
