Step to import a FFlex body
1. Click the Import icon of the FFlex group in the Flexible tab.
2. Pick a point in the Working Plane. It is the position of the FFlex body reference frame.
3. Select an input file that has the FE mesh information.
• You can select either a NASTRAN format (*.bdf, *.dat) or an ANSYS format (*.cdb).
• Change the file extension as needed.
4. Click OK, then you can see the mesh of FFlex body displayed in the Working Window.
Figure 2 Import dialog box
• File Name: Enters the file name and its path.
• Import Type: Shows the format of Source file.
• RecurDyn displays an error message if the data in the FE file information does not match the selected file format.
• The expected file format depends upon the selected file extension as well as the selected Import Type.
• Body Name: Specifies the name of FFlex body that will be created.
• Origin: Specifies a point located at the origin of the FE mesh. All nodes are defined with respect to the Origin point.
• Ref. Marker: Defines the orientation of the origin of FE mesh as well as its location. The FFlex body reference frame is coincided with the reference marker.
• Geo. RefFrame: Means a geometry reference frame. If the user selects this option, all nodes in the imported FFlex body are located with respect to the reference frame of geometry.
• Option
• Allow Null-Property/Material: The default materials and properties are generated if a FE model has only connection information without any real material or property information.
• Create Beam Element with Pre-Stress: If this option is check, user can create beam element with pre-stress. This option is not supported for other element type.
• Generate Patch Set from Node/Element Set: If this option is check, user can create patch set from node or element set in file.
• Unit of Source: Defines the base units used to create the FE mesh.
• Use Force Unit: If the user checks this option, the force unit will be used for converting the Young's modulus of material.
