UNITS
From version 9.4 onwards, T/HIS tries to keep track of the units for each curve's X and Y axis. For every data component that T/HIS can read from an Ansys LS-DYNA results file, one of the following basic units is stored for the curve's X and Y axis.

When a curve operation is carried out on curve which has either the X or Y axis unit defined, the units for the output curve(s) are also calculated. If a curve operation is carried out using 2 or more input curves with different units and the result is a curve with inconsistent units, then the units are set to zero.
If one of the inputs is a constant then it assumed to be unitless.
