Add Nodal Load dialog

This dialog is used to apply a load at the selected nodes.

Opens when the Nodal Load tool is selected on the Node ribbon tab in the Loads group.

Note: This tool is inactive if the active load case is a parametric load case (e.g., seismic, response spectrum, or time history).

Positive force values are taken in the direction of the axes. Positive moment directions are taken counter-clockwise about the axes.

Property Value
Load Select the load case or load group to which this load will be added.
Tip: The current load case or group is the default selection. This is displayed in the program status bar and can be changed on the View ribbon tab in the Active Load group.
Coordinate System Select either the WCS (global coordinate system) or a user-created coordinate system.
Note: Capital XYZ are used to designate global coordinate systems where as lowercase xyz are used to designate user coordinate systems.
Direction Select the method by which the loads are oriented:
  • Parallel to axes – loads parallel to the selected axes system
  • Pointing to origin – the x direction loads are point from the loaded node to the selected origin axes. Other load directions are applied in orthogonal directions with the Y axis in a plane of this load x axes and the global Y direction.

Direction options for nodal loads with respect to the selected Reference CS

FX/Fx Magnitude of force in the global X direction or in the local x direction for a user-coordinate system.
FY/Fy Magnitude of force in the global Y direction or in the local y direction for a user-coordinate system.
FZ/Fz Magnitude of force in the global Z direction or in the local z direction for a user-coordinate system.
MX/Mx Magnitude of moment in the about the global X axis or about the local x direction for a user-coordinate system.
MY/My Magnitude of moment in the about the global Y axis or about the local y direction for a user-coordinate system.
MZ/Mz Magnitude of moment in the about the global Z axis or about the local z direction for a user-coordinate system.
