Computational domain

This section explains the preparation of surfaces to create the domain. This is done with the operations splitting, combining and renaming of the surfaces.

Vortex Shedding

1. Select Split/Combine Geometry or Grid in the Mesh Panel.
2. Select CAD Surfaces vortex_shedding in the Geometric Entities Panel.
3. Select Split by Angle from the Operation drop-down list in the Properties Panel.
4. Enter 75 deg for Angle, click Split by Angle. Seven new CAD Surfaces are created in the Geometric Entities Panel.
5. Rename the CAD Surfaces vortex_shedding_01,vortex_shedding_02, vortex_shedding_03, vortex_shedding_04, vortex_shedding_05, vortex_shedding_06, and vortex_shedding_07 as vortex_shedding_side1, vortex_shedding_side2, vortex_shedding_bot, vortex_shedding_top, vortex_shedding_inlet, vortex_shedding_outlet, and vortex_shedding_cylinder respectively .

Note: Splitting of the surfaces can also be done by mouse selection using the Split by Mouse option from the Method drop-down list in the Geometry Tab of Properties Panel.
