*INITIAL CONDITIONS
Set TYPE=TEMPERATUREto give initial temperatures. The STEP and INC parameters can
be used in conjunction with the FILE parameter to define initial tem peratures from the results or
output database file of a previousABAQU S/Standardheat transfer analysis.
Set TYPE=VELOCITY to prescribe initial velocities. Initial velocities should be defined in
the global directions, regardlessof the use of the *TRAN SFORM option.
STEP
This parameter is used only with the FILE parameter. The parameter specifies the step in the
results file of a previous ABAQUS analysis from which prescribed fields of TYPE=FIELD,
TYPE=PRESSURE STRESS, or TYPE=TEMPERATUREare to be read. It can also specify the
step in the output database file of a previous ABAQUS analysis from which presc ribed fields of
TYPE=TEMPERATUREare to be read.
INC
This parameter is used only with the FILE parameter. The parameter specifies the increment in
the results file of a previous ABAQUS analysis from which pre scribed fields of TYPE=FIELD,
TYPE=PRESSURE STRESS, or TYPE=TEMPERATUREare to be read. It can also specify the
increment in the output databasefile of a previous ABAQUS analysis from which prescribed fields
of TYPE=TEMPERATUREare to be read.
Optional parameters:
ABSOLUTE EXTERIOR TOLERANCE
Thisparameter is relevant only for use with the INTERPOLATEparam eter. Set this parameter equal
to the absolute value (given in the units used in the model) by which nodes of the current m odel may
lie outside the region of the model in the output database specified by the FILE parame ter. If this
parameter is not used or has a value of 0.0, the EXTERIOR TOLERANCE paramet er will apply.
EXTERIOR TOLERANCE
Thisparameter is relevant only for use with the INTERPOLATEparam eter. Set this parameter equal
to the fraction of the averageelem ent sizeby w hichnodes of the current model may lie outside the
region of the elements of the model in the output database specified by the FILE pa rameter. The
default value is 0.05.
If both tolerance parameters are specified, ABAQUS uses the tightertolerance.
FILE
Set this parameter equal to the name of the resultsfile from which initial field variable or pressure
stress data are to be read. Set this parameter equal to the name of the results fileor output database
file from which initial temperature dataare to be read. Thisparameter must be used in conjunction
with the STEP and INC parameters.
GEOSTATIC
This parameter is used only with TYPE=STRESS to specify that a geostatic stress state, in which
stresses vary with elevation only,is being defined.
