Connections
Connections are used to define the association of different regions of interest between parts in an assembly.
Virtual Connector
Virtual connectors are rigid imaginary parts created between selected faces/spots representing geometrical support of the connector.
Imported Bushing
Defines directional stiffness between two parts that lie within specified diameter from the bushing center via importing a .csv file.

Connections
Connections are used to define the association of different regions of interest between parts in an assembly.
- Regular Connections
  Regular connections can be used to define contact-based connections between parts in an assembly.
- Precise Connections
  SimSolid creates precise connections on the fly during geometry import and are grouped under the Precise connection folder.
- Welds
  Welding is a process that joins materials, usually metals by using heat or pressure.
- Adhesives
  Structural adhesives are simulated as thin layers of adhesive material associated with a connection.
- Virtual Connector
  Virtual connectors are rigid imaginary parts created between selected faces/spots representing geometrical support of the connector.
  - Pin
    Connect an arbitrary number of coaxial cylindrical faces.
  - General Connector
    Create a rigid imaginary rigid part between arbitrary faces/spots.
  - Remote Support
    Connect faces or spots to a ground support.
  - Bushing
    Define directional stiffness and inertia coefficients.
  - Imported Bushing
    Defines directional stiffness between two parts that lie within specified diameter from the bushing center via importing a .csv file.
  - Rivet
    Connect multiple part with rivets of a given diameter.
  - Remote Mass
    Connect faces/spots of a single part to a remote mass represented as mass and moments of inertia.
  - Joints
    Connect faces/spots that can have relative motion in the form of displacements and/or rotations.
  - Cable/Rod
    Create a virtual cable/rod with finite or infinite stiffness between two different parts or between a single part and ground. Virtual cable/rod is applied on spots.
  - Superelements
    Used to import a DMIG file which is the reduced representation of the behavior and performance of a structure or a part of a structure.
  - Shock Absorbers
    Create a virtual shock absorber with finite stiffness and damping between two different parts or between a single part and ground. Virtual shock absorber is applied on spots.
- Connection Review

Frequently Asked Questions

Imported Bushing

Defines directional stiffness between two parts that lie within specified diameter from the bushing center via importing a .csv file.

In the Project Tree, click the Connections workbench.
Select > Bushing > Imported Bushing
In the dialog, click Import from CSV.
Browse to the desired .csv file in the File Explorer.
Click Open.
Optional: Edit the connector.
1. Select a row in the dialog and click Edit Connector.
  
  Tip: You can also double-click on a row to edit. Both methods will display an Imported bushing dialog.
2. In the dialog, edit desired values (coordinate system, coordinates, diameter, linear and angular stiffness).
3. Click OK.
Check the warnings and correct them. A warning can appear in following situations.
- If the coordinate system specified in the .csv is not recognized.
- Failure to map points on the parts. Edit the coordinates and diameter in such cases.
- If points are mapped between more than two parts.
Click OK.

Imported Bushing CSV File Format

CSV file format for importing bushings.

The CSV file contains one header row and one or more additional data rows. Data values are as follows:

X, Y and Z – Numeric values. Spatial location of bushing center.
Diameter – Numeric value. Points will be mapped on the parts within the specified diameter from the bushing center.
Stiffness Linear/angular X, Y, and Z – Numerical values.
Coordinate system - Coordinate system name. Name of the bushing coordinate system to resolve the stiffness. Global coordinate system will be used if the coordinate system fields are empty in the .csv.
Note: Spatial location of bushing center will still be in global coordinate system.
