Applying a Remote Mass (Rigid Connection) to a Face, Edge, or Vertex

To apply a remote load (rigid connection) toa face, edge, or vertex:

  1. In the Simulation study tree, right-click the External Loads icon an select Remote Load/Mass PM_remote_load-mass.gif.
  2. Under Type, select Load/Mass (Rigid connection).
  3. In the graphics area, select the faces, edges, or vertices to which you want to apply the remote mass. For nonlinear studies, you can select only faces to apply remote mass.
  4. Set the Reference Coordinate System to Global (default global), or User defined. For User defined, click inside the Select a Coordinate System PM_force_coordinate_system.gif box , then select a coordinate system from the flyout FeatureManager tree.
  5. Under Location, do the following:
    1. Select the desired Units PM_units.gif for length .
    2. Type the coordinates of the point of application of the remote force in the X-Location PM_remote_load_x_location.gif, Y-Location PM_remote_load_y_location.gif, and Z-Location PM_remote_load_z_location.gif boxes.
  6. Under Force, do the following:
    1. Set Units PM_units.gif to the desired unit of force.
    2. Click the force components that you want to specify and type in their values.
  7. Select Moment, then do the following:
    1. Set Units PM_units.gif to the desired unit of moment.
    2. Click the moment components that you want to specify and type in their values.
  8. Select Mass, then do the following:
    1. Set Units PM_units.gif to the desired unit of mass.
    2. Type the mass value in the Remote Mass box remotemass.png.
    3. Type the moments of inertia with respect to axes XPM_moment_inertia_x.gif , YPM_moment_inertia_y.gif , ZPM_moment_inertia_z.gif, and the products of inertia with respect to axes XYPM_moment_inertia_xy.gif, YZPM_moment_inertia_yz.gif , XZPM_moment_inertia_xz.gif in the respective boxes.
      The mass moments of inertia should be calculated with respect to a coordinate system that is centered at the CG, and has X-Y-Z axes parallel to the X-Y-Z axes of the global, or user defined coordinate system.
  9. Click PM_OK.gif.
