Reaction Force

You can list reaction forces on selected entities for an active static, nonlinear, drop test and dynamic study. The software lists the X-, Y-, Z-components of the reaction force, and the resultant reaction force on the selected entities and on the entire model as well.


  • Plane, Axis or Coordinate System . Select to list the results relative to the selected entity.

  • Units . Sets the output units.

  • Faces, Edges, or Vertices . Lists the selected entities.

  • Components. Lists the selected components.

  • Plot Step Sets the time step number at which you want to list the reaction force. This option is available only with nonlinear, drop test and dynamic studies.

  •  . Displays the time corresponding to the selected plot step. Available for nonlinear, drop test and modal time history studies.

  • . Displays the frequency corresponding to the selected plot step. Available for harmonic and random vibration studies.

  • Update. Updates the results based on the current selected entities.

  • Reaction force and Reaction moment. Lists the reaction forces and moments of the selected entities and the entire model.

Display Options

Display resultant forces. When checked, the three force vectors (X-, Y- and Z- components) are converted to a resultant force vector. Only the resultant force vector is displayed.

To list the reaction forces:

  1. After running the analysis, right-click the Results folder and select List Result Force.


Click Simulation, Result Tools, Reaction Force.


Click Reaction Force (Simulation toolbar).

  1. In the PropertyManager, set Units to the desired output units.

  2. In the graphics area, select the desired entities for Selection (Face, Edge, Vertex) .

  3. Click Update.

View the results under Reaction force.

  1. Click .
