*INITIAL CONDITIONS
INPUT
Set this parameter equal to the name of the alternate input file containing the data lines for this
option. See “Input syntax rules,” Section 1.2.1 of the ABAQUS Analysis User’s Manual, for the
syntax of such file names. If this parameter is omitted, it is assumed that the data follow the keyword
line.
INTERPOLATE
Include this parameter in conjunction with the FILE, STEP, and INC parameters to indicate that the
temperature field needs to be interpolated between dissimilar meshes. This feature is used to read
temperatures from an output database file generated during a heat transfer analysis. This parameter
and the MIDSIDE parameter are mutually exclusive. If the heat transfer analysis uses first-order
elements and the current mesh is the same but uses second-order elements, use the MIDSIDE
parameter instead.
MIDSIDE
This parameter applies only to ABAQUS/Standard analyses.
Include this parameter in conjunction with the FILE, STEP, and INC parameters to indicate
that midside node temperatures in second-order elements are to be interpolated from corner
node temperatures. This feature is used to read temperatures from a results or output database
file generated during a heat transfer analysis using first-order elements. This parameter and the
INTERPOLATE parameter are mutually exclusive.
NORMAL
This parameter applies only to ABAQUS/Standard analyses.
This parameter can be used only with TYPE=CONTACT to specify that the nodes in the node
set (or the contact pair, if a node set is not defined) are bonded only in the normal (contact) direction
and are allowed to move freely in the tangential direction. If the nodes in the node set (or the contact
pair) are to be bonded in all directions, this parameter should be omitted.
REBAR
This parameter can be used with TYPE=HARDENING in ABAQUS/Standard,
TYPE=SOLUTION, or TYPE=STRESS.
When used with TYPE=HARDENING in ABAQUS/Standard, it specifies that rebars are in a
work hardened state, with initial equivalent plastic strain and, possibly, initial backstress.
When used with TYPE=SOLUTION, it specifies that rebars are being assigned initial solution-
dependent state variable values.
When used with TYPE=STRESS, it specifies that prestress in rebars is being defined. When
performing an ABAQUS/Standard analysis, some iteration will usually be needed in this case
to establish a self-equilibrating stress state in the rebar and concrete. The *PRESTRESS HOLD
option can be useful for post-tensioning simulations (see “Defining rebar as an element property,”
Section 2.2.4 of the ABAQUS Analysis User’s Manual).
