Computational domain

This section describes the steps involved in the preparation of surfaces to create the domain. This is done with the operations - splitting, combining, and renaming of the surfaces. The CAD Surfaces imported into Simerics-MP+ are shown in in the Figure 11.361.

Propeller Surfaces

Select Split/Combine Geometry or Grid in the Mesh Panel.
Select CAD Surfaces propeller in the Geometric Entities Panel.
Select Split Disconnected from the Operation drop-down list in the Properties Panel, click Split Disconnected.
Rename the four new CAD Surfaces propeller_01, propeller_02, propeller_03 and propeller_04 as propeller_side1, propeller_side2, propeller_top and propeller_propeller respectively in the Geometric Entities Panel.

´	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.
