Heat Flux dialog box (Nastran)

Type
Type	Specifies how the heat flux load is defined.Uniform element/Uniform element — spatial: Defines a uniform heat flux into elements. The spatial type lets you map the field directly to a global or local coordinate system.For more information, see QBDY3 in the Simcenter Nastran Quick Reference Guide.Variable element/Variable element — spatial: Defines grid point heat flux into elements. The spatial type lets you map the field directly to a global or local coordinate systemFor more information, see QBDY2 in the Simcenter Nastran Quick Reference Guide.Grid/Grid — spatial: Defines a uniform heat flux into a set of grid points. The spatial type lets you map the field directly to a global or local coordinate system.For more information, see QHBDY in the Simcenter Nastran Quick Reference Guide.Note: Spatial boundary conditions are best when you want to use externally generated results or other data to define the load.
Destination Folder
Load Container	Specifies the folder in the Simulation Navigator in which the boundary condition will be stored. The list includes the root container and existing folders that you created using the New Folder command. Examples of a root container include Load Container, Constraint Container, and Simulation Object Container.
Folder Manager	Displays a hierarchical listing of existing folders. To create a new folder, right-click any level of the hierarchy and choose New Folder.
Model Objects
Group Reference	Lets you apply the heat flux load to a group.For more information, see Group Reference options.
Select Object	Lets you select the geometry or FE entities on which the load will be applied. Use the Excluded options to remove individual entities, such as nodes or edges, from your selection.
Stacked Smart Selector Methods	Opens the Smart Selector Methods dialog box where you can specify a progression of smart selection filters.For more information, see Smart Selector Methods dialog box.
Control Point
Select Object	Available if you select Uniform element or Uniform element-spatial from the Type list.Lets you select an optional control point for the heat flux load. The temperature at the node is used to multiply the heat flux terms. This option corresponds to the CNTRLND field on the QBDY3 bulk data entry.
Magnitude
Q0 – Heat Flux	Specifies the magnitude of the heat flux load. For more information, see Additional magnitude options.
Distribution
Appears when Type is set to any non-spatial heat flux load.
Method	Defines how the heat flux load is distributed over the selected objects.Constant: Applies the magnitude to the object as a constant value.Spatial: Lets you specify a unitless field to map the heat flux to the elements or nodes. A field is always mapped to global or Cartesian coordinates, even if it was defined in cylindrical or spherical coordinates.
Distribution Field
Appears when Distribution is set to Spatial for any non-spatial heat flux load.
Specify Field	Defines how the heat flux load is distributed over the elements in the selected area.
Card Name	Displays the name of the solver card for the load.
