It is the function to input the heat flux load. It can be applied to nodal points / edges / faces. Heat flux is used to model heat input through the surface of an object.
It is used as a load vector in heat transfer analysis. The heat flux is entered as the unit time energy per time x unit area (Watt/Area). A time function can also be applied.

Name

Enter the name of the heat flux to be defined.

Type

Select the type of target objects to which heat flux will be applied.  Only the edges of 2D elements can be selected.

 Heat Flux

 Enter the heat flux value to the selected target objects.

 Uniformly Distributed Load

Load the heat flux uniformly.  If this is not selected, the heat flux will be loaded in a linear varying form.

Area Factor

Enter Area factor when Nodal method is used.

 Base Function

Set a spatial function or a non-spatial function as a base function to be applied to the heat flux.

 Q1

Enter the heat flux value when Uniformly Distributed Load is selected.

 Q2 - Q4

For a linearly varying distribution,  enter the heat flux values sequentially.

Time Function

Select the function to be applied to time.

 Global Time

The time applied to the time function is based on the total analysis time.

 Local Time

The time applied to the time function is based on the subcase time.

Thermal Load

Register the specified heat flux to a desired load set.  The user may assign any name to the load set.
