Comments
 Specific TH output variables can be requested or output variable groups can be requested to output all the output variables listed for that group.
 The time history output frequency must be entered in the Engine file using /TFILE for time history file output or /ABF for Altair Binary Format output.
 The time history file (*T01, *.thy) stores impulses and rotational impulses. When reading the time history file, HyperGraph automatically takes the derivative of the impulses to calculate the forces and moments. If using the ASCII time history results, the forces and moments will need to be calculated by taking the derivative of impulses versus using a 3^{rd} party tool.
 The Altair binary format (*.abf) contains forces and moments output directly from Radioss.
 Calculating forces and moments using the derivative of the impulses, can cause nonzero force values at time=0. If needed, the nodal animation force output, /ANIM/VECT/* can be postprocessed.
 FI, MI, FXI, FYI, FZI, MXI, MYI, and MZI are the forces applied by interfaces TYPE14 or TYPE15 on the envelope surface (if available).
