ABAQUS Volume II: I–Z - Manual (Page 305)

*PRESSURE STRESS
Data lines to define pressures using the data line format:
First line:
1. Node set or node number. If a node set label is given, all nodes in this set must have identical
initial pressures.
2. Reference pressure value (positive in compression). If the AMPLITUDE parameter is present,
this value will be modified by the AMPLITUDE specification.
Repeat this line as often as necessary to define the pressure at different nodes or node sets.
To read pressures from an ABAQUS/Standard results file (FILE):
No data lines are used when pressure data are read from a results file.
Data lines to define equivalent pressure stresses using user subroutine UPRESS:
First line:
1. Node set or node number. If a node set label is given, all nodes in this set must have identical
initial equivalent pressure stress values.
Repeat this line as often as necessary. UPRESS will be called for each node listed.
