Heat Flux

To specify the load Heat flux, use one of the following methods:

Command Line:	FEMAHFLUX
Main Menu:	AutoFEM \| Loads/Restraints \| Heat flux
Icon:

The load Heat flux allows the user to specify the amount of heat transferred across the unit surface area per unit of time, that is, define a specific heat flux.

Heat flux can be applied to faces of the model. For selecting faces, use the automenu option:

	Loads/Restraints on faces
	Select all faces

Selected elements are added to the list.

In the properties window of the load Heat flux it is required to specify the following parameters:

•the load magnitude;

•units: W/m2, W/cm2, BTU/s*in2.

Negative value of the heat flow signifies that through the specified face the body looses the energy.

In the 3D scene Heat flow is shown in the following way:

A typical sequence of steps for specifying Heat flux:

1.Initialize the command «Heat flux» .

2.Select a face.

3.Specify the magnitude of load.

4.Specify units.

5.Complete the command.
