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.

Mixing Tank Surfaces

Select CAD Surfaces mixingtank in the Geometric Entities Panel.
Select Split/Combine Geometry or Grid in the Mesh Panel.
Select Split Disconnected from the Operation drop-down list in the Properties Panel, click Split Disconnected. Two new CAD Surfaces are created in the Geometric Entities Panel.
Rename the CAD Surfaces mixingtank_01 as mixingtank_stator and mixingtank_02 as mixingtank_rotor.

Rotor Surfaces

Select CAD Surfaces mixingtank_rotor in the Geometric Entities Panel.
Select Split/Combine Geometry or Grid in the Mesh Panel.
Select Split by Angle from the Operation drop-down list in the Properties Panel and enter 90 deg for Angle, 4 for Maximum No. of Splits, click Split by Angle. Five new CAD Surfaces are created in the Geometric Entities Panel.
Rename the CAD Surfaces mixingtank_rotor01 as mixingtank_rotor_mgi_statorside, mixingtank_rotor02 as mixingtank_rotor_mgi_statorbot, mixingtank_rotor03 as mixingtank_rotor_mgi_statortop.
Select CAD Surfaces mixingtank_rotor and mixingtank_rotor04 in the Geometric Entities Panel.
Select Combine from the Operation drop-down list in the Properties Panel.

Stator Surfaces

Select CAD Surfaces mixingtank_stator in the Geometric Entities Panel.
Select Split/Combine Geometry or Grid in the Mesh Panel.
Select Split by Angle from the Operationdrop-down list in the Properties Panel and enter 90 deg for Angle, 4 for Maximum No. of Splits, click Split by AngleSplit by Angle. Five new CAD Surfaces are created in the Geometric Entities Panel.
Select CAD Surfaces mixingtank_stator02 and rename as mixingtank_stator_mgi_rotorside.
Select CAD Surfaces mixingtank_stator03 and mixingtank_stator04 in the Geometric Entities Panel.
Enter 75 deg for Angle and 2 for Maximum No. of Splits, click Split by Angle. Four new CAD Surfaces are created in the Geometric Entities Panel.
Select CAD Surfaces mixingtank_stator_03_01, mixingtank_stator_04_01 and rename as mixingtank_stator_mgi_rotortop, mixingtank_stator_mgi_rotorbot.
Select CAD Surfaces mixingtank_stator_03_02, mixingtank_stator_04_02. Select Combine from the Operation drop-down list in the Properties Panel, click Combine and rename as mixingtank_stator_shaft.
Select CAD Surfaces mixingtank_stator and mixingtank_stator01 in the Geometric Entities Panel.
Select Combine from the Operation drop-down list in the Properties Panel, click Combine and rename as mixingtank_stator_wall.
