Heat Power

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

Command Line:	FEMAHPOWER
Main Menu:	AutoFEM \| Loads/Restraints \| Heat power
Icon:

The load Heat power allows the user to define:

•volume power of thermal energy sources;

•amount of heat transferred through an arbitrary surface per unit of time, called a power of heat flow (heat power).

Heat power can be applied to a body, a face, an edge or a vertex of a model. For selecting elements of model use the automenu option:

	Loads/Restraints on bodies
	Loads/Restraints on faces
	Loads/Restraints on edges
	Loads/Restraints on vertices
	Select all faces

Selected elements are added to the list.

In the properties window specify:

•magnitude of load;

•units: W, BTU/sec.

The negative value of this thermal load signifies that a body looses the energy.

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

A typical sequence of steps for specifying the load "Heat power":

1.Initialize the command "Heat power" .

2.Select a body, a face, an edge or a vertex.

3.Specify the magnitude of load.

4.Specify the units.

5.Complete the command.
