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.

Summary of steps in the video above:

1. Face Selection Filter -> select inlet surface -> (right-click) Create Named Selection -> inlet
2. Repeat the steps above to create named selections for the outlet1, outlet2 and wall_artery
3. Body Selection Filter -> select the whole body -> (right-click) Create Named Selection -> fluid_zone
