*RADIATE

Set REGION TYPE=LAGRANGIAN (default) to apply the radiation cond ition 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 to apply the radiation condition to a slidingboundary region.

The edge of a sliding boundary region will slide over the material. Adaptive meshing will occur

along the edge and in the interior of the region. Meshconstraints are ty pically applied on the edge

of a sliding boundary region to ﬁx it spatially.

Set REGION TYPE=EULERIAN to apply the radiation condition to an E ulerian boundary

region. This option is used to create a boundary re gion across which material can ﬂow. Mesh

constraints must be used normal to an Eulerian boundary region to allow m aterial 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. Elementnumber or elem ent set name.

2. Radiationtype (see Part VI, “Elements,” of the ABAQUS Analysis User’s Manual).

3. Referenceambient temperature value, .(Unitsof .)

4. Emissivity, .

Repeat this data line as often as necessary to deﬁne radiation conditions.
