Building the Mesh

This section describes the step-by-step procedure for preparing the mesh for the vortex shedding model. The mesh is created using the General Mesher in Simerics-MP+. The settings for the mesh generation are explained in the following steps:

Vortex Shedding

Select General Mesher in the Mesh Panel.
Select vortex_shedding_bot, vortex_shedding_cylinder, vortex_shedding_inlet, vortex_shedding_outlet, vortex_shedding_side1, vortex_shedding_side2 and vortex_shedding_top under CAD Surfaces in the Geometric Entities Panel.
Click Add Surfaces of the CAD Surfaces in the Properties Panel.
Select Normal Mode under Setup Options and Absolute under Cell Size Specification.
Enter Maximum Cell Size as 0.05, Minimum Cell Size as 0.001 and Cell Size on Surfaces as 0.05 .
Select Box Zone under Create a Refinement Zone drop-down list.
Enter the parameters under the Refine Zone Options list as follows:
- Cell Size: 0.025
- First Corner: -1, -1.5, 0 m
- Diagonal Corner: 10, 1.5, 0.05 m
Click Create Mesh. A new mesh vortex_shedding is created under Built Meshes in the Geometric Entities Panel.
The meshed volume vortex_shedding is generated under Volumes.

Note: In Cell Size SpecificationAbsoluteoption is used to control the mesh based on dimension of the geometry and uniformity.

The created mesh is shown below:
