Definition view

These options vary depending on whether you select a component or a connection.

Definition view (components)

These options set characteristics of the component FEM files that appear in the generated FEM assembly.

Option	Description
Name	Sets the name of this component. The name becomes the file name of the FEM component that appears in the Simulation Navigator for the assembly FEM file that NVH Composer generates.Note: The component name must be unique. Otherwise, the assembly FEM file cannot be generated.
Component	Lets you select an existing Pre/Post FEM or assembly FEM file.
Mesh	Lets you select a Nastran file that contains finite element data that was generated either from Pre/Post or other CAE software.
Connection Points Required	Specifies whether your NVH assembly uses hard points. Hard points are used as target locations to create a bump stop, bushing, latch, or spring connection. You can create hard points using selection recipes as explained in Exporting selection recipes as hard points. When you define a connection, you enter the name of the hard point as it exists in the exported selection recipe.If you set this to No, hard point names that you enter cannot be checked, and connections that use hard points become invalid when you use the Check Assembly command .
Connection Points	Sets the location and name of the hard points XML file, which is a selection recipe of exported hard points.

Definition view (connections)

These options set the characteristics of the universal connections that connect the components in the assembly. These are the same characteristics that you can set in the universal connection dialog boxes, such as targets, locations, and physical properties.

Option	Description
Name	Sets the name of this connection.Note: The connection name must be unique.
Type	Specifies the connection type. In the Simulation Navigator for the generated assembly FEM file, NVH Composer groups the connections types into folders named for the connection type. For example, all connections assigned the Latch type appear in a folder named Latch Connections. Bolt****Latch, which corresponds to the Spring universal connection.Spring****Bump Stop, which corresponds to the Bushing universal connection.Weather Strip, which corresponds to the Sealing universal connection.BushingKinematicSeam Weld
Property	Available when Type is any connection other than Kinematic.Specifies a property that is defined in the connection database. The settings defined for the property are used when realizing (meshing) the connection, and the name of the property defines the name of the realized connection elements.
****
Component 1Component 2Component 3	Specifies the components (Target in the universal connections dialog boxes) that the connection connects. Depending on the connection type, universal connections can connect a maximum of three components. The components are the flanges or targets of the connection.This list is populated with the components that you add to the assembly layout.Note: Component 3 applies only to Bolt connections.
Support	Available when Type is set to Latch, Spring, Bump Stop, Bushing, and Kinematic.Specifies whether the connection is Single Point or Local Spider.For more information, see Bearing / Bushing / Damper / Spring Connection dialog box or Kinematic / Rigid Connection dialog box.
Point Name/Coord (mm)	Sets coordinates or a hard point by name, depending on the connection type.You can type a coordinate, or you can type the name of a hard point that is contained in the hard point file associated with the component.
PID	Sets the physical property ID (PID) of the component. For Pre/Post FEM files, you can find this PID in the Physical Property Table Manager dialog box. In the Physical Property Table Manager dialog box, the PID is the label that corresponds to the type of element, such as PSHELL.For meshes that you import, you can find the PID in the Nastran .dat or .bdf file.To enter multiple PIDs, separate each PID with a comma.
Max Search Distance	Available when Support is set to Local Spider.For information, see Max. Search Distance in the Bearing / Bushing / Damper / Spring Connection dialog box dialog box.
Ring Options	Available when Support is set to Local Spider.For information, see Ring Options in the Bearing / Bushing / Damper / Spring Connection dialog box dialog box.
Expansion Radius	Available when Support is set to Local Spider, and Ring Options is set to Expansion Radius.For information, see Ring Options in the Bearing / Bushing / Damper / Spring Connection dialog box dialog box.
Expansion Radius Factor	Available when Support is set to Local Spider, and Ring Options is set to Expansion Radius Factor.For information, see Ring Options in the Bearing / Bushing / Damper / Spring Connection dialog box dialog box.
Connect Spiders To	Available when Support is set to Local Spider.For information, see Connect Spiders To in the Bearing / Bushing / Damper / Spring Connection dialog box dialog box.
Target Search Range	Available when Support is set to Local Spider, and Connect Spiders To is set to All Selected Targets.For information, see Target Search Range in the Bearing / Bushing / Damper / Spring Connection dialog box dialog box.
****
Step Length	Corresponds to Step Length in the Seam Weld Connection or Sealing Connectiondialog box. For more information, see Adhesive / Clinch / Crimp / Rivet / Sealing / Seam Weld / Spot Weld Connection dialog box.
Shank diameter	Corresponds to Shank Diameter in the Bolt Connection dialog box. For more information, see Bolt Connection dialog box (universal connections).
Head diameter	Corresponds to Header Diameter in the Bolt Connection dialog box. For more information, see Bolt Connection dialog box (universal connections).
Weatherstrip Part****Weatherstrip Part 2	Opens the part file that contains the geometrical line of the weather stripping or other part for the sealing connection you are defining. Whether you use one Weatherstrip Part or two depends on how you want to define the sealing connection:To define the projection direction from one location point on the first line to one location point on the second line, use two weatherstrip parts. This is equivalent to selecting the With Orientation check box on the Sealing Connection dialog box.To define the projection direction orthogonally starting from the definition point, use one weatherstrip part. This is equivalent to clearing the With Orientation check box on the Sealing Connection dialog box.If you do not have a part file for the geometrical line, you can create a selection recipe for an element edge that defines the same line. Weatherstrip Part and Curve/Element edge Recipe are mutually exclusive.
Curve/Element edge Recipe****Curve/Element edge Recipe 2	Sets the name of the selection recipe that contains the element edge that defines the geometrical line of the weather stripping for the sealing connection you are defining.Whether you use one Curve/Element edge Recipe or two depends on how you want to define the sealing connection, as explained for Weatherstrip Part.
Local Axis	Applies to Latch, Spring, Bump Stop, Bushing, and Kinematic connections.For information, see Axis Type in the Bearing / Bushing / Damper / Spring Connection dialog box or the Kinematic / Rigid Connection dialog box.
Translational DOF****Rotational DOF	Applies to Kinematic connections.For information, see Axis Type in the Kinematic / Rigid Connection dialog box.
