Load Step: CRADIATE

In the CRADIATE dialog, define the *CRADIATE cards on node sets.

To open this dialog from the Load Step dialog, select CRADIATE from the tree and a load collector from the Load collector table.

Load Step: CRADIATE: Define Tab

In the Define tab, define a *CRADIATE card on node sets only.

*CRADIATE on individual nodes is not supported.

Use the Define CRADIATE on: Node sets option to define *CRADIATE on node sets.

Note: Loads created on sets are not graphically displayed. Therefore, when you review a load collector in the Step Manager, only loads created on individual entities are highlighted. For loads defined on sets, the underlying nodes or elements are highlighted.

This dialog has a node sets drop down menu containing a list of the existing node sets. It also has a data line input table with the following columns:

Table 1.
Column	Description
Nodeset	The name of the node sets. Node sets are added or removed using → or ←, respectively.
Area	The area associated with the nodes.
Sink temp	Ambient reference temperature.
Emissivity	Surface emissivity.

For tips on entering information and navigating in the Define tab, see Step Manager Tab Environment.

The Define CRADIATE on: Node sets option has the following buttons:

Table 2.
Button	Action
Review/Reset Set	Reviews the selected node sets by highlighting them in the HyperMesh graphics. Right-click Review to clear the review selections.
Create/Edit Set..	Opens the Entity Sets panel in HyperMesh. When you finish creating/editing the set, click return. The Step Manager is updated with the new set appearing in the node set list.
→	Add the selected node set from the drop-down menu to the data line table on the right.
←	Delete the selected node set from the data line table.
Review	Reviews the selected node set in the data line table. Right-click Review to clear the highlighted selections.
Update	Updates the HyperMesh database with the data lines defined in the table. By default, HyperMesh does not create a display for loads defined with sets.

Load Step: CRADIATE: Delete Tab

In the Delete tab, delete *CRADIATE and other loads.

There are three deletion options:

Table 3.
Option	Description
All loads in current collector	The Delete button deletes all the loads from the current load collector.
All 'CFILM' in current collector	The Delete button deletes only *CRADIATE loads from the current load collector.
By selection	The Pick Loads button opens the HyperMesh load selector panel. Pick the loads you want to delete and click proceed. The corresponding Reset button resets the selected loads. The Delete button deletes the selected loads.

Load Step: CRADIATE: Parameter Tab

In the Parameter tab, define optional parameters for the *CRADIATE card.

The supported parameters include: Amplitude curve, OP, and Region Type.

Click Update to activate the optional parameter selection in the HyperMesh database.
