Cavitation over an Orifice: Exercise 2—Preparing the Mesh
1. In the Flow Analysis Tree select Domains.
2. In the Properties panel, Model tab, for Mesh Generation, specify the following values:
Maximum Cell Size0.005
Minimum Cell Size0.001
Cell Size on Surfaces0.005
Create a Refinement ZoneCylindrical Zone
Cell Size—0.0025
Top Circle Center—0.0140, 0, 0
Bottom Circle Center—0.032, 0, 0
Zone Radius—0.006
3. Click Generate Mesh to create the mesh for the fluid domain. If the Info dialog box opens, click Yes to convert all the units.
4. Click in the Graphics toolbar to display the style elements. Select No Hidden, Hidden Line, or Wireframe to display the mesh.
5. Clear CAD Bodies and Flow Analysis Bodies.
6. Select Domains.
7. In the Functions panel click Turn on/off view properties and select the following from the list: Hide all surfaces, Hide all grids, and Hide all outlines.
8. Under Boundary Conditions, Interface, select the boundary ORIFICE_CAVITATION.
9. In the Properties panel, View tab, set Surface, Grid, and Outline to Yes. The mesh for the boundary ORIFICE_CAVITATION appears in the graphics window.
