Definition Modal Load

Nodal Load type

The user can make a Cartesian load on a node. A modal load case has one or more loads of Nodal Load type.

•     RFlex Body: Displays a name of selected RFlex body.

•     Load Name: Displays a name of modal load case. This name can be modified in the Modal Load Case dialog box.

•     Node ID: Writes a node id of selected RFlex body.

•     FX, FY, FZ: Force vector on the node id with respect to the reference frame of RFlex body.

•     TX, TY, TZ: Torque vector on the node id with respect to the reference frame of RFlex body.

•     : Executes Node Selection Dialog.

•     Add: Adds a load of the Nodal Load type.

•     Delete: Deletes selected loads of the Nodal Load type.

•     Close: Closes this dialog box.

Modal Load type

The user can directly define a converted modal force vector. The load vector size is [(6+nmode) x 1]. The “nmode” is a number of all modes in a selected RFlex body.

•     RFlex Body: Displays a name of selected RFlex body.

•     Load Name: Displays a name of modal load case. This name can be modified in the Modal Load Case dialog box.

•     Mode Seq.: Displays all modes of selected RFlex body and a generalized force and torque for the rigid motion of RFlex body.

•     Value: Inputs desired values.
