RADIATE
Set REGION TYPE=LAGRANGIAN (default) to apply the radiation conditi on to a
Lagrangian boundary region. The edge of a Lagrangian boundary region will follow the material
while allowing adaptive meshing along the edge and within the interior of the region.
Set REGION TYPE=SLIDING t o apply the radiation condition to a sliding boundary region.
The edge of a sliding boundary region will slide ove r the material. Adaptive meshing will occ ur
along the edge and in the interior of the region. Mesh constraints are typically applied on the edge
of a sliding boundary region to fix it spatiall y.
Set REGION TYPE=EULERIAN to apply the radia tion condition to an Eulerian boundary
region. This option is used to create a boundary region across which material can flow. Mesh
constraints must be used normal to an Eulerian boundary region to allow material to flow through
the region. If no mesh constraints a re applied, an Eulerian boundary region will behave in the same
way as a sliding boundary region.
Data lines to define radiation conditions:
First line:
1. Element number or elem ent set nam e.
2. Radiation type (see Part VI, “Elem ents,” of the ABAQUS Analysis User’s Manual).
3. Reference ambient temperature value,
.(Unitsof .)
4. Emissivity,
.
Repeat this data line as often as necessary to define radiation conditions.
