The output data of Modal Force is as follow.
•FM: The magnitude of the translational force.
•FX / FY / FZ: The summation of the force acting at the node with respect to RFlex body reference frame. This force is calculated in USUB.
•TM: The magnitude of the rotational force.
•TX / TY / TZ: The summation of the torque acting at the node with respect to RFlex body reference frame. This force is calculated in USUB.
•Modal Force: The force value by each mode. This force is calculated in USUB.
