Optional parameter:
NAME
Set this parameter equal to the name used to identify the step on the output database. Step names in
the same input file must be unique.
NLGEOM
Set NLGEOM=YES (default) to indicate that geometric nonlinearity should be accounted for
during the step (stress analysis and fully coupled thermal-stress analysis only). Once the NLGEOM
option has been switched on, it will be active during all subsequent steps in the analysis. Set
NLGEOM=NO to perform a geometrically linear analysis during the current step.
The default value for the NLGEOM parameter in an ABAQUS/Explicit analysis is YES
unless the ABAQUS/Explicit analysis is an import analysis, in which case the default value of the
NLGEOM parameter is the same as the value of the parameter at the time of import.
Optional data lines:
First line:
1. Subheading for this step.
The subheading can be several lines long, but only the first 80 characters of the first line will be saved
and printed as a subheading.
