Data Mapper Reference by Type

This section provides information on the actions and properties available for all types of mappers. The data mapper properties include source settings and mapped field specifications.

表 1. Action Menu
Map Data Executes the mapping operation.
Delete Deletes the data mapper, without deleting any mapped data. To delete mapped data, first use the Clear Mapped Fields action, available for the parent Data Mappers node.
表 2. Surface, Volume, and Beam Data Mapper Properties
[Source] Specifies the source from which to map data. The name of this property changes to one of the following, based on the type of data mapper:
Source Surfaces For Surface Data Mappers, you can specify one or more surfaces from which to map data. Source surfaces can either be 2D regions, region boundaries, part surfaces, or surfaces defined on an imported CAE model.
Source Volumes For Volume Data Mappers, you can specify one or more volumes from which to map data. Source volumes can either be Simcenter STAR-CCM+ regions or parts, or volumes defined on an imported CAE model.
Source Beams For Beam Data Mappers, you can specify a single beam from which to map data. The source beam can only be an imported CAE beam.
Source Phases For Parcel Data Mappers, you can specify any Lagrangian phases defined in the simulation.
Source Stencil Specifies the location where the solution data is available on the source mesh. If the solution available on the source mesh was computed using finite volume (FV) techniques, the source stencil is most likely either a cell or a face. If the solution available on the source mesh was computed using finite elements (FE) techniques, the source stencil is typically a vertex. Choosing the wrong combination of stencils reduces the integrity of the mapping operation.
Face Instructs the data mapper to map field data available at the source mesh faces. Typically, this stencil is appropriate for surface data mappers that map data from surfaces of a finite volume mesh, for example boundaries or part surfaces of a Simcenter STAR-CCM+ FV model.
Cell Instructs the data mapper to map field data available at the source mesh cell centroids. Typically, this stencil is appropriate for volume data mappers that map data from volumes (cells) of a finite volume mesh, for example regions or parts of a Simcenter STAR-CCM+ FV model.
Vertex Instructs the data mapper to map field data available at the source mesh vertices. Typically, this stencil is appropriate for surface, volume, and beam data mappers that map data from a finite element source mesh. For example, part surfaces, parts, or regions of Simcenter STAR-CCM+ FE models, surfaces or volumes of imported FE models, imported beams.
Scalar Functions Specify scalar and/or vector fields for mapping. The data mapper interpolates the specified fields, available at the source faces, cells, or vertices as specified in the Source Stencil property, to the target mesh.
Vector Functions
Mapped Names The fields that you specify for mapping become available as field functions when you execute the data mapper or the Pre-Register Mapped Fields option. See Data Mappers Reference. The mapped data field functions have the default name, Mapped<Target_stencil><Field_name>. Using this property, you can specify/edit an alternative name for each of the field functions generated by the data mapper.
Representation For Simcenter STAR-CCM+ source meshes, this property allows you to select the representation to get source data from, which could be either the Volume Mesh representation or any representations available in a simulation history file. See Recording And Viewing Solutions. This property has no effect when the source mesh is an imported CAE model.
Use original mesh When activated, instructs the data mapper to use the original mesh as the reference mesh for mapping. When deactivated, the data mapper uses the current mesh as the reference mesh for mapping. See Mapping Between Structure And Fluid Grids.
Verbosity Controls the level of verbosity of the selected data mapper. When activated, the Output window displays additional details on the mapping process, such as the percentage of target source faces, cells, or vertices that is mapped successfully.
表 3. Boundary Samples Data Mapper Properties
Source Boundary Samples Specifies the boundary particle tracks from which to map data
Scalar Functions Specify scalar and/or vector fields for mapping. The data mapper interpolates the specified fields, available from the parcels at the source faces, to the target mesh.
Vector Functions
Mapped Names The fields that you specify for mapping become available as field functions when you execute the data mapper or the Pre-Register Mapped Fields option. See Data Mappers Reference. The mapped data field functions have the default name, BoundaySamplesDataMapper<n><Field_name>. Using this property, you can specify/edit an alternative name for each of the field functions generated by the data mapper.
Representation For Simcenter STAR-CCM+ source meshes, this property allows you to select the representation to get source data from., At present, Volume Meshis the only option. See Recording And Viewing Solutions. This property has no effect when the source mesh is an imported CAE model.
Verbosity Controls the level of verbosity of the selected data mapper. When activated, the Output window displays additional details on the mapping process, such as the percentage of target source faces, cells, or vertices that is mapped successfully.
表 4. Tabular Data Mapper Properties
Source Table Allows you to provide source data in tabular form. You can only select XYZ tables created in Simcenter STAR-CCM+ (see Creating a Table ), or file tables imported from external files (see Reading a Table Data File). The table must have at least four named columns. Three of the columns specify an x, y, and z location, and the fourth column specifies the value of a certain field at that location. Additional columns can specify the values of other scalar fields at the prescribed locations.
Source: X-Coordinate Allows you to select the source table column that contains the X-coordinates.
Source: Y-Coordinate Allows you to select the source table column that contains the Y-coordinates.
Source: Z-Coordinate Allows you to select the source table column that contains the Z-coordinates.
Source: Data Allows you to specify the source table column that contains the values of the field to map. You can select multiple columns to specify multiple fields for mapping.
Mapped Names Allows you to specify/edit names for each of the output field functions generated by the data mapper for each of the Source(s): Data set.
Verbosity Controls the level of verbosity of the selected data mapper. When activated, the Output window displays additional details on the mapping process, such as the percentage of target source faces, cells, or vertices that is mapped successfully.
