Position, velocities, acceleration, deformation, strain and stress of nodes and elements which belong to an FE body are reported in the Motion Postprocessor as shown in the table below. Output nodes can be selected in the Motion Postprocessor application.

Parameter | Symbol | Description | Dimension | |
Position | , | The position and angle of the node. The angle for nodes of beam or shell elements is represented by the ZXZ (PSI-THETA-PHI) Euler angle in Equation 2–60 ~ Equation 2–62. Otherwise, the angle for nodes of solid elements will report a zero value [For Node]. |

Velocity | The translational velocity of the node [For Node]. | Length/Time | ||
Angular_Velocity | The angular velocity of the node in its own reference frame. For nodes of solid elements, the vector is measured in the inertia reference frame. [For Node] | Radian/Time | ||
Acceleration | The translational acceleration of the node. [For Node] | Length/Time^2 | ||
Angular_ Acceleration | The angular acceleration of the node in own reference frame. For nodes of solid elements, the vector is measured in the inertia reference frame. [For Node] | Radian/Time^2 | ||
Deformation | The translational and rotational deformation of the node. The deformation is measured in the user-defined reference frame that is defined in the Postprocessor and its default is the inertia reference frame. The rotational deformation for nodes of beam or shell elements is represented by the ZXZ (PSI-THETA-PHI) Euler angle in Equation 2–60 ~ Equation 2–62. Otherwise, the rotational deformation for nodes of solid elements will report a zero value. [For Node] |

Contact_Pressure | The pressure due to the contact force of a node. First, the total area for the node is calculated from the surface area of adjacent elements including the node. The total area is then averaged with the number of adjacent elements. The contact pressure is calculated by dividing the contact force applied on the node by the averaged area.
