11.1.2.1. Method RIGID to FFLEX

If a Rigid body is selected as a source body for G-Manager, FFlex and RFlex body can be converted. When the target body is FFlex body, two methods are supported to convert FFlex body.

11.1.2.1.1. (1) FFlex : Mesh

When the target body is FFlex body, if the user wants to mesh a rigid body using RecurDyn/Mesher, Mesh type can be used. In this case, only enters to Mesh mode.

  • Target Converting Body: Selects a target body type. In this case, please select FFlex.

  • Type: Selects a method how to change from Rigid to FFlex. In this case, please select Mesh.

  • Options

    • Target Geometry: Selects a target geometry to mesh. This cannot be changed in Mesh mode.

  • Additional Options

    • Use Force Connector of Connecting Parameter: Determines how to connect between the dummy body and nodes. The default is unchecked. For more information, click here.

  • Assist Modeling: some items can be maintained after converting process.

    • Name: Maintains the name of source body.

    • Initial Velocity: Maintains the initial velocity of source body.

    • Joint: Maintains Joint entities related to the source body.

    • Force: Maintains Force entities related to the source body.

    • Geo Contact: Maintains Geo Contact entity related to the source body. Other Contact entities are not supported.

  • Create CAD Data File: If this option is checked, the CAD file for the original rigid body is created in the defined directory when converting to other types.

11.1.2.1.2. (2) FFlex : Swap using Mesh Data File

When the target body is FFlex body, if the user wants to swap with a mesh data file, Swap using Mesh Data File type can be used.

  • Target Converting Body: Selects a target body type. In this case, please select FFlex.

  • Type: Selects a method how to change from Rigid to FFlex. In this case, please select Swap using Mesh Data File.

  • Options

    • Mesh Data File Path: Defines a path of the file that is used to swap.

    • Reference: Defines a reference frame that is used to swap.

  • Additional Options

    • Swap Options: When Rigid body is converted to FFlex body, some options are needed. For more information about this dialog, please refer to Import dialog box. in FFlex.

    • Use Force Connector of Connecting Parameter: Determines how to connect between the dummy body and nodes. The default is unchecked. For more information, click here.

  • Assist Modeling: some items can be maintained after converting process.

    • Name: Maintains the name of source body.

    • Initial Velocity: Maintains the initial velocity of source body.

    • Joint: Maintains Joint entities related to the source body.

    • Force: Maintains Force entities related to the source body.

    • Geo Contact: Maintains Geo Contact entity related to the source body. Other Contact entities are not supported.

      • In the case of Geo Surface Contact, a Patch Set is created for the whole surface of the base or action geometry.

      • In the case of Geo Curve Contact, a Line Set is created for the first edge of the base or action geometry.

  • Create CAD Data File: If this option is checked, the CAD file for the original rigid body is created in the defined directory when converting to other types.
