*STEP

Beginning a step in an ABAQUS/Explicitanalysis

Optional parameter:

NAME

Set this parameter equal to the name used to identifythe step on the output database. Stepnames in

the same input ﬁle must be unique.

NLGEOM

Set NLGEOM=YES (default) to indicate that geometric nonlinearity should be accounted for

duringthe 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 currentstep.

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 cas et he 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 charactersof the ﬁrst line will be saved

and printed as a subheading.
