*PRESSURE STRESS
are being reset to new values (not to initial conditions) via OP=NEW, the AMPLITUDE parameter
described above applies.
Required parameter for reading equivalent pressure stresses from the results file:
FILE
Set this parameter equal to the name of the results file (including the optional .fil extension) from
which the data are read. See “Input syntax rules,” Section 1.2.1 of the ABAQUS Analysis User’s
Manual, for the syntax of such file names.
Optional parameters for reading equivalent pressure stresses from the results file:
BSTEP
Set this parameter equal to the step number (of the analysis whose results file is being used as input
to this option) that begins the history data to be read. If no value is supplied, ABAQUS/Standard
will begin reading pressure data from the first step available on the results file.
BINC
Set this parameter equal to the increment number (of the analysis whose results file is being
used as input to this option) that begins the history data to be read. If no value is supplied,
ABAQUS/Standard will begin reading pressure data from the first increment available (excluding
any zero increments) for step BSTEP on the results file.
ESTEP
Set this parameter equal to the step number (of the analysis whose results file is being used as input
to this option) that ends the history data to be read. If no value is supplied, ESTEP is taken as equal
to BSTEP.
EINC
Set this parameter equal to the increment number (of the analysis whose results file is being used as
input to this option) that ends the history data to be read. If no value is supplied, EINC is taken as
the last available increment of step ESTEP on the results file.
Required parameter for defining data in user subroutine UPRESS:
USER
Include this parameter to indicate that user subroutine UPRESS will be used to define equivalent
pressure stress values. UPRESS will be called for each node given on the data lines. If values are
also given on the data lines, these values will be ignored. If a results file has been specified in
addition to user subroutine UPRESS, values read from the results file will be passed into UPRESS
for possible modification.
