Mesh
The meshing process is:
1. Create named selections (inlet, outlet1, outlet2, wall_artery and fluid_zone).
2. Change the Global Mesh settings.
3. Add Local Sizings to refine the mesh (inflation mesh and body sizing).
4. Preview automatically generated inflation mesh and finally, generate the volume mesh.
The videos below show you how to create the mesh for the fluid domain.
