7.4.11.1. FFlex Body
The lists of FFlex Bodies include a result set about each body as position, velocity and acceleration. The lists of energy data. There are 3 types, Kinetic Energy, Potential Energy, Strain Energy.
Pos_TM: The magnitude of the translational displacement of the center marker in the inertia reference frame.
Pos_TX, Pos_TY, Pos_TZ: The x, y, and z components of the translational displacement of the center marker in the inertia reference frame.
Pos_PSI, Pos_THETA, Pos_PHI: The 3-1-3 Euler angle of the center marker measured in the inertia reference frame.
Pos_YAW, Pos_PITCH, Pos_ROLL: The 3-2-1 Euler angle of the center marker measured in the inertia reference frame.
Vel_TM: The magnitude of the translational velocity of the center marker in the inertia reference frame.
Vel_TX, Vel_TY, Vel_TZ: The x, y, and z components of the translational velocity of the center marker in the inertia reference frame.
Vel_RM: The magnitude of the angular velocity of the center marker in the inertia reference frame.
Vel_RX, Vel_RY, Vel_RZ: The x, y, and z components of the angular velocity of the center marker in the center marker reference frame.
Acc_TM: The magnitude of the translational acceleration of the center marker in the inertia reference frame.
Acc_TX, Acc_TY, Acc_TZ: The x, y, and z components of the translational acceleration of the center marker in the inertia reference frame.
Acc_RM: The magnitude of the angular acceleration of the center marker in the inertia reference frame.
Acc_RX, Acc_RY, Acc_RZ: The x, y, and z components of the angular acceleration of the center marker in the center marker reference frame.
Kinetic Energy: Sum of all kinetic energy of all nodes. The reference frame is ground inertia.
Potential Energy: Sum of all potential energy of all nodes. The reference frame is ground inertia
Strain Energy: Sum of all strain energy of all nodes. This value is calculated in same method as the strain energy of output Node.
