Global (Whole Model) DataComponents

Global (whole model) data components

This section describes the data components available for the "whole" model. These can only be processed as numerical values in WRITE and XY_DATA .

Global data components are all extracted from the complete state ( .PTF ) file.

Raw components written by Ansys LS-DYNA are shown THUS , those calculated or derived by D3PLOT are shown oblique THUS .

Energies

KE_KINETIC_ENERGY

IE_INTERNAL_ENERGY

TE_TOTAL_ENERGY

The total kinetic energy.

The total strain and other non-kinetic energy.

The sum of the two terms above.

Velocities

VX_X_VELOCITY

Average X velocity of the whole model

VY_Y_VELOCITY Average Y velocity of the whole model
VZ_Z_VELOCITY Average Z velocity of the whole model
VR_VELOCITY_RESULTANT Vector sum of above (computed by D3PLOT)

Mass values

MASS The sum of all material masses.
Note: This only contains mass from solid, shell, beam and thick shell materials. Lumped masses, stonewalls, and any other entity types which might contribute mass to the model are not included. Thus, for most models, this is an underestimate.

Momentum values (From mass * velocity)

MX_X_MOMENTUM Mass * average X velocity
MY_Y_MOMENTUM Mass * average Y velocity
MZ_Z_MOMENTUM Mass * average Z velocity
MR_MOMENTUM_RESULTANT Vector sum of the above

Note: The mass used here is the computed mass above, so the computed momenta may be an underestimate.
