Mapping the Surface and Beam Data
To exchange data between the curve zones (the 1D beams) and the surface zones (the blade boundaries), you create data mappers. Each rotor blade requires two data mappers: a surface data mapper, with a beam target specification, and a beam data mapper.
To interpolate the fields computed at the blade boundaries to
their beam counterparts:
-
Create a surface data mapper for each blade and add a beam target specification
to the data mapper.
For information on data mappers, see Data Mappers Reference.
To interpolate the beam data to their corresponding boundaries
in Simcenter STAR-CCM+:
- Create a beam data mapper for each blade.
You can populate the sources and targets for each surface and
beam mapper using predefined curve-to-surface and surface-to-curve Field
Treatments. The surface-to-curve field treatment converts the 3D
surface forces to nodal forces and moments applied to the beam. The curve-to-surface
field treatment maps beam displacements and rotations to displacements on the
vertices of the blade boundary. The mesh morpher uses the mapped displacements to
update the fluid mesh.
To specify the sources and targets for each beam mapper:
- Right-click the and select .
-
Select the [Curve to Surface Mapping] node and set the
following properties:
Property Setting Source blade 1 beam zone Target blade 1 boundary zone Mapper beam data mapper - Using the method above, create curve to surface mapping treatment for each of the remaining rotor blades.
To specify the sources and targets for each surface
mapper:
- Right-click the Field Treatments node and select .
-
Select the [Surface to Curve Mapping] node and set the
following properties:
Property Value Source blade 1 boundary zone Target blade 1 beam zone Mapper beam data mapper
To create the external beam regions in Simcenter STAR-CCM+:
-
Right-click the [Link 1] node and select
Create External
Parts.
This action populates the Regions node with the external beam regions.
