Mapped Panel dialog box

Use this dialog box to create structural panel simulation objects from groups of acoustic fluid nodes that are mapped to structural nodes. You can also export the panels to an external file to use in your own panel contribution analysis application.

Source Acoustic Groups
Lets you manage groups that contain acoustic fluid nodes.
Select Groups	Opens the Group Selection dialog box where you can select existing groups or create new groups.
Remove selected groups from list	Removes selected groups from the list.Tip: Use the Ctrl or Shift keys to select multiple groups.
Remove all groups from list	Removes all groups from the list.
Structural Targets
Lets you specify structural entities for the mapping algorithm.
All Structural Meshes	Includes all 2D or 3D structural meshes.
Custom Selection	Lets you select individual structural entities.
Select Object	Appears when Custom Selection is selected.Lets you select individual structural entities in the graphics window or from the Simulation Navigator.Note: You can select the following entities:ElementsElement facesMeshesSelection recipes that contain at least one structural 2D or 3D element, element face, or mesh.
Mesh Mapping
Number of Influencing Nodes	Sets the number of nodes to be considered within the maximum search distance.
Maximum Distance	Sets the maximum search distance between nodes in regions of a structural mesh and an acoustic fluid mesh. The search distance is the radius of a sphere centered at a source node (acoustic fluid node). The software loops over target nodes (structural nodes) within the maximum search distance from a source node, and ignores any target nodes outside the search distance.The following process details this mapping method with a coarse mesh as a source mesh (thick black) and a fine mesh as a target mesh (thin green).Unmapped meshes**(1) Element edge of target mesh, (2) Element node of target mesh, (3) Element edge of source meshMaximum distance searchThe software searches for source nodes within a maximum search distance from target nodes.(4) Search area over the source node defined by Maximum DistanceTarget node identificationWithin the maximum search distance, the software considers up to the number of target nodes that you define in 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 target nodes**
Output
Lets you manage the output group names.Input Acoustic Group lists each source acoustic group.Output Structural Group lists the name of the group that contains the mapped structural nodes. By default, the name is prefixed with STR.Output Structural Panel lists the label of the structural panel that the software uses for a Panel simulation object of type Panel on Nodes/Element Faces. The unique name (maximum of eight characters) corresponds to the NAMEi field of the PANEL bulk entry. By default, the panel name is PANELid, where id starts with 001 or with the highest ID +1 of the existing panels. If the automatic id exceeds 999, the software truncates the panel name to be within the eight-character limit.Note: When no matching structural nodes exist, the software does not create empty output structural groups.You can rename any output name by double-clicking a cell in the Output Structural Group or Output Structural Panel column. You can also rename an output name by right clicking a cell and choosing Use Input Group Name as Panel Name. The software replaces the Output Structural Panel name with the Input Acoustic Group name.Note: Because of Simcenter Nastran requirements:The software truncates Output Structural Panel names to eight characters.You must replace embedded blanks in Output Structural Panel names with characters.Right-click a column head or empty table cell and choose Export to Browser to view the group and panel names in a different format, or Export to Spreadsheet to save the group and panel names in a separate file.
Export Panels	Lets you export the panels to a Nastran BDF (.bdf) file or data file (.dat).Note: When you export panels to a file that already contains PANEL bulk entries, the software appends the new bulk entries to the existing bulk entries.
File Name	Available when the Export Panels check box is selected.Lets you enter or select a Nastran BDF or data file name.Type a path and file name, or click Browse to open the File to export dialog box where you can select the file type and enter a new file name or select an existing file to update.
