Reaction Forces

Displays the Reaction Forces and Reaction Moments for the applied constraints on faces, edges, and vertices. Calculation of reaction forces includes the force acting along bounding edges and vertices. When constraints share edges or vertices, the global summation of forces could appear out of balance. The reaction forces and moments can be inconsistent if the applied constraint shares a surface, edge, or vertex with another constraint.

Access:

Simulation browser Constraint node Context menu Reaction Forces

Reaction forces, for the Fixed, Pin, and Frictionless constraints, are displayed based on the selected constraint.

Reaction forces do not display values unless a simulation has been run. If the constraint is suppressed, the command is not enabled.

Reaction Forces are included, by default, in generated reports. You have the option to exclude this information from the report.

Reaction Force  
  Total Displays the total reaction force.
  X Displays the X component reaction force.
  Y Displays the Y component reaction force
  Z Displays the Z component reaction force
Reaction Moment  
  Total Displays the total magnitude of the reaction moment about the constraint centroid
  X Displays the value of the reaction moment component about the x-axis of the constraint centroid.
  Y Displays the value of the reaction moment component about the y-axis of the constraint centroid.
  Z Displays the value of the reaction moment component about the z-axis of the constraint centroid.
