Optional parameters
- AMPLITUDE
-
Set this parameter equal to the name of the
AMPLITUDE option that gives the variation of the ambient temperature
with time.
If this parameter is omitted in an
Abaqus/Standard
analysis, the reference magnitude is applied immediately at the beginning of
the step or linearly over the step, depending on the value assigned to the AMPLITUDE parameter on the
STEP option (see
Defining an Analysis).
If this parameter is omitted in an
Abaqus/Explicit
analysis, the reference magnitude is applied immediately at the beginning of
the step.
- OP
-
Set OP=MOD (default) for existing
CRADIATE definitions to remain, with this option modifying existing
radiation conditions or defining additional radiation conditions.
Set OP=NEW if all existing
CRADIATE definitions applied to the model should be removed.
-
PHANTOM
-
This parameter applies only to Abaqus/Standard analyses.
Set
PHANTOM=NODE
to specify radiation conditions and associated sink temperatures at a phantom node
that is originally located coincident with the specified real node in an enriched
element.
Set
PHANTOM=EDGE
to specify radiation conditions and associated sink temperatures at a phantom node
located on an element edge between the two specified real corner nodes in an enriched
element. This setting applies only to nodes with both pore pressure and temperature
degrees of freedom.
- REGION TYPE
-
This parameter applies only to
Abaqus/Explicit
analyses.
This parameter is relevant only for concentrated radiation conditions
applied on the boundary of an adaptive mesh domain. If concentrated radiation
conditions are applied to nodes in the interior of an adaptive mesh domain,
these nodes will always follow the material.
Set REGION TYPE=LAGRANGIAN (default) to apply a concentrated radiation condition to a
node that follows the material (nonadaptive).
Set REGION TYPE=SLIDING to apply a concentrated radiation condition to a node that can
slide over the material. Mesh constraints are typically applied to the node to
fix it spatially.
Set REGION TYPE=EULERIAN to apply a concentrated radiation condition to a node that can
move independently of the material. This option is used only for boundary
regions where the material can flow into or out of the adaptive mesh domain.
Mesh constraints must be used normal to an Eulerian boundary region to allow
material to flow through the region. If no mesh constraints are applied, an
Eulerian boundary region will behave in the same way as a sliding boundary
region.
