INITIAL CONDITIONS
Set TYPE=PORE PRESSURE to give initial pore fluid pressures for a coupled pore fluid
diffusion/stress analysis in ABAQUS/Standard.
Set TYPE=POROSITY to give initial porosity values f or materials defined with the
*
EOS
COMPACTION option in ABAQUS/Explicit.
Set TYPE=PRESSURE STRESS to give initial p ressure stresses for a mass diffusion analysis
in ABAQUS/Standard. The STEP and INC parameters can be used in conjunction with the
FILE parameter to define initial v alues of pressure stress from the results file of a previous
ABAQUS/Standard stress/displacem ent analysis.
Set TYPE=RATIO to give initial void ratio val ues for a coupled pore fluid diffusion/stress
analysis in ABAQUS/Standard. The USER parameter can be used with this parameter to define
initial void ratio values in user subroutine VOIDRI.
Set TYPE=REF COORDINATE to define the reference mesh (initial metric) for membran e
elements in ABAQUS/Explicit. If a reference mesh is specified for an element, no initial stress or
strain can be specified for the same element. The initial stress and strain are computed automatically
to account for deformation from the reference to the initial configuration.
Set TYPE=RELATIVE DENSI TY to give initial relative densi ty values for materials defined
with the
*
POROUS METAL PLASTICITY option.
Set TYPE=ROTATING V ELOCITY to prescribe initial velocities in terms of an angular
velocity and a global translational velocity.
Set TYPE=SATURATION to give initial saturation values for the analysis of flow through a
porous medium in ABAQUS/Standard. If no initial s aturation values are given on this option, the
default is fully saturated conditions (saturation of 1.0). For partial saturation the initial saturation
and the pore fluid pressure must be consistent in the sense that the pore fluid pressure must lie within
the range of absorption and exsorption value s for the initial saturation value. If this is not the case,
ABAQUS/Standard will adjust the saturation value as needed to satisfy this requirement.
Set TYPE=SOLUTION to give initial values of solution-dependent state variables. The
REBAR and, in ABAQUS/Standard, USER parameters can be used w ith this parameter. If
TYPE=SOLUTION is used without the USER param eter, element average quantities of the
solution-dependent state variables must be defined on each data line.
Set TYPE=SPECIFIC ENERGY to give initial specific energy values for materials defined
with the
*
EOS option in ABAQUS/Explicit.
Set TYPE=SPUD EMBEDMENT to give the initial embedment for a spud can in an
ABAQUS/Aqua analysis.
Set TYPE=SPUD PRELOAD to give the initial preload value for a spud can in an
ABAQUS/Aqua analysis.
Set TYPE=STRESS to give initial stre sses. (These stresses are effective stresses when the
analysis includes pore fluid flow.) The GEOSTATIC; the REBAR; the SECTION POINTS; and,
in ABAQUS/Standard, the USER parameters can be used with this param eter. If TYPE=STRESS
is used without the USER parameter, it is assumed that the stress components are defined on
each data line in the order given for the element type, as defined in Part VI, “Elements,” of the
ABAQUS Analysis User’s Manual.
