Heat Power

The Heat Power PropertyManager lets you apply heat power to the vertices, edges, faces, and components.

The specified value is applied to EACH entity. For example, if you apply a heat power of 1,000 Watts to a vertex, 2 faces, and a component, the total heat power applied is 4,000 Watts. The value of the heat power can be positive or negative. A positive value indicates heating and a negative value indicates cooling (heat absorption). Heat power is used for thermal studies only.

Defining Heat Power

To define heat power:

  1. Do one of the following:
    • In the Simulation study tree, right-click Thermal Loads and select Heat Power .
    • Click Simulation > Loads/Fixture > Heat Power.
    • Click Heat Power (Simulation toolbar).
    The Heat Power PropertyManager appears.
    To select all faces exposed to outside at once, click Select all exposed faces. To delete a face, right-click the face and select Delete.
  2. In the graphics area, select the desired vertices, edges, faces, and components.
  3. Under Heat Power, do the following:
    1. Set Units to the desired unit system.
    2. Enter a value for the Heat power in the selected unit system.
    3. To define a time-dependent heat power, click Use Time Curve time_curve.png Button then click Edit to import or define a time curve. The value of the heat power at any time instant is calculated by multiplying the specified heat power value by the corresponding Y value of the time curve. This option is available for transient thermal studies only.
    4. To define a temperature-dependent heat power, click Use Temperature Curve then click Edit to import or define a temperature curve. The value of the heat power at a given temperature is calculated by multiplying the heat power value by the corresponding Y value of the temperature curve.
  4. To control the heat power condition by a thermostat, do the following:
    1. Click Thermostat (Transient).
    2. Click in Sensor (select a vertex) select_vertex.png and select the location of the thermostat.
      Make sure to first click in the Sensor (select a vertex) box before selecting a vertex for the sensor. Otherwise, the selected vertex appears in the Selected entities box.
    3. Select the unit for the Lower bound temperature and type the desired value in the value box.
    4. Select the unit for the Upper bound temperature and type the desired value in the value box.
  5. Click .
The specified value is applied to each selected vertex, edge, surface, and component.
