Vortex Shedding: Exercise 2—Preparing the Mesh
A mesh is a computational grid inside, outside, or both inside and outside any closed geometry defined by a CAD surface.
Generating the Mesh
1. In the Flow Analysis Tree, select Domains.
2. In the Properties panel, Model tab, for Mesh Generation, type the following values:
Cell Size SpecificationAbsolute
Maximum Cell Size0.1
Minimum Cell Size0.001
Cell Size on Surfaces0.05
3. Create two refinement zones, type the following values:
Refine Zone OptionsBox Zone
Cell Size—0.025
First Corner— -1, -1.5, 0
Diagonal Corner— 10, 1.5, 0.05
4. Click Generate Mesh to create the mesh for the fluid domain. If the Info dialog box opens, click Yes to convert all the units.
Viewing the Mesh
1. Click in the Graphics toolbar to display the style elements. Select No Hidden, Hidden Line, or Wireframe to display the mesh.
2. Clear CAD Bodies and Flow Analysis Bodies.
3. Select Domains.
4. In the Properties panel, View tab, set Surface, Grid, and Outline to Yes. The mesh for the boundary VORTEX_SHEDDING appears in the graphics window.
