The scale and combine is used in fatigue analysis where the finite element
model is solved for one or more stress states (channels) and extruded
into a scaled time history of stresses by scaling each channel with a
loading definition, and combining each scaled channel into a single tensor.

The loading definition is a series of numeric scale factors which
represent a fatigue cycle of the FE model. Since finite element
analysis is often time-intensive, loading scales allow for the model to
be solved for one state and extruded in a fatigue time history.
In order to generate a valid scale and combine, the loading must be
proportional so that the stresses from each channel can be superimposed
without incurring a phase difference. Hence SCALECOMBINE should only be
used in conjunction with elastic FEA where the stress-strain
relationship is linear.
IMPORTANT:

SCALECOMBINE requires getRPT.m in order to interpret the RPT file(s).Also, make sure all channel and loading files are in your working directory.
