Mesh Mapping Data dialog box

Use this dialog box to map regions between model meshes, intermediary meshes, or an intermediary mesh and a model mesh.

Note:

You can map more than two sets of meshes at a time, as long as the source data is the same. However, if you want to specify different parameters for each mapping, you must create additional maps using this dialog box.

****
Name	Renames the mesh mapping data node that appears in the Simulation Navigator.
Mesh Mapping
Mapping Method	Allows you to select the mapping method between regions of model meshes, intermediary meshes, or between an intermediary mesh and a model mesh.Maximum DistanceLoops over source nodes within a maximum search distance from a target node.The following steps detail this mapping method with a fine mesh as a source mesh (thin green) and a coarse mesh as a target mesh (thick black).Unmapped meshes.(1) Element edge of source mesh, (2) Element node of source mesh, (3) Element edge of target meshSearch for source nodes within a maximum search distance from target nodes.(4) Search area over the target node defined by Maximum DistanceWithin the maximum search distance, the software considers up to the number of source nodes that you define under Number of Influencing Nodes. For example, if Number of Influencing Nodes is set to 4, only one node is within the Maximum Distance. This is why only one node is mapped within each Maximum Distance sphere.(5) Influencing nodesNote: In a different example, if the software finds more than one node within the search region, the software applies weighting based on distance.When the search region contains more nodes than the specified number of influencing nodes, the software only considers the nearest nodes.Mapped source and target nodes*Conservative Maximum DistanceLoops over target nodes within a maximum search distance from a source node. The mapping is considered to be conservative because the integral of the data sources is conserved.The following steps detail this mapping method with a fine mesh as a source mesh (thin green) and a coarse mesh as a target mesh (thick black).Unmapped meshes.*(1) Element edge of source mesh, (2) Element node of source mesh, (3) Element edge of target meshSearch for target nodes within a maximum search distance from source nodes.****Source node distributed to target nodes.Within the maximum search distance, the software considers up to the number of target nodes that you define under Number of Influencing Nodes. For example, if Number of Influencing Nodes is set to 4, the load on one source node is shared among 4 target nodes.****Note: When no target nodes exist within the search area, the software ignores the source node.Mapped source and target nodes after weighting based on distance was applied.****Note: For demonstration purpose, the source nodes are scaled in this image. The larger nodes are just more weighted.Nearest NeighborLoops over source nodes near a target node to find the closest source node. You use this method when there is a one-to-one correspondence between target and source nodes.MatrixAppears when the Model and Load Pre-processing node lists an Input File node.Uses a matrix file created with, for example, the Mesh Mapping dialog box, to map data to the regions of a model mesh.Note: The Conservative Maximum Distance method gives more accurate results than the Maximum Distance method because the Conservative Maximum Distance method ensures that more source nodes are assigned to target nodes. However, this method is also more computationally expensive.You typically use the Conservative Maximum Distance method when you map 2D electromagnetic analysis result data to a 3D structural mesh.
Number of Influencing Nodes	Appears when Mapping Method is set to Maximum Distance or Conservative Maximum Distance.Sets the number of nodes to be considered within the maximum search distance.
Maximum Distance	Appears when Mapping Method is set to Maximum Distance or Conservative Maximum Distance.Sets the maximum search distance between nodes of regions of intermediary meshes or between an intermediary mesh and a model mesh.The search distance is defined as the radius of a sphere centered:At a target node when you use the Maximum Distance method.At a source node when you use the Conservative Maximum Distance method.Any nodes outside the search distance will be ignored.
Mesh Mapping Matrix FileAppears when Mapping Method is set to Matrix.Lets you map data from a matrix file to the regions of a model mesh.
Infers Relative Path	The software infers and stores the path to the file that you specify relative to the Simulation file. If the location of the file changes, the software uses the stored relative path information to try to locate the file. For more information, see Relative path support for external files.Caution: This option is reserved for a future enhancement and is not currently functional.
Browse	Opens the Select File window where you can filter for applicable file types, navigate to, and select an external results file.
Transfer From
Transfer From	Available for all Mapping Method options except Matrix.Intermediary EntitiesAllows you to select FE entities from the intermediary mesh.Entire MeshSelects the entire intermediary mesh or the output mesh from a previous operation.Model EntiesAllows you to select FE entities from the model mesh.
Select Source	Appears when Intermediary Entities is selected in the Transfer From group.
Select Model	Appears when Model Entities is selected in the Transfer From group.
Stacked Smart Selector Methods	Appears when Intermediary Entities or Model Entities is selected in the Transfer From group.Opens the Smart Selector Methods dialog box where you can specify a progression of smart selection filters.For more information, see Smart Selector Methods dialog box.
Transfer To
Transfer To	Model EntitiesLets you map the data from the intermediary mesh to a model mesh.Intermediary EntitiesAvailable for all Mapping Method options except Matrix.Lets you map the data from regions of the intermediary mesh to regions on the same or different intermediary meshes.Same as SourceAvailable for all Mapping Method options except Matrix.Lets you map the data from elements, element faces, or a mesh to the same entities.For example, you may want to map vibrations (displacements, velocities, accelerations, or forces) from a rotating mesh, such as a tire mesh, to the same stationary mesh.
Select Model	Appears when you select Model Entities in the Transfer To group.Lets you select a model mesh.
Stacked Smart Selector Methods	Appears when you select Model Entities in the Transfer To group.Opens the Smart Selector Methods dialog box where you can specify a progression of smart selection filters.For more information, see Smart Selector Methods dialog box.
Select Intermediary	Appears when you select Intermediary Entities in the Transfer To group.Lets you select FE entities from the intermediary mesh.
Stacked Smart Selector Methods	Appears when you select Intermediary Entities in the Transfer To group.Opens the Smart Selector Methods dialog box where you can specify a progression of smart selection filters.For more information, see Smart Selector Methods dialog box.
