Heat Power

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

The value of the heat power can be positive or negative. A positive value indicates heating and a negative value indicates cooling (heat absorption).

You can apply heat power for thermal studies only.

Defining Heat Power

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

To open the Heat Power PropertyManager, do one of the following:

  • In the Simulation study tree, right-click Thermal Loads and select Heat Power .
  • In the Simulation toolbar, click Heat Power .
  1. Under Selected Entities, select the required vertices, edges, faces, and components.
    For beams and trusses, select Joints or Beams .
    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.
    Select Per item, to apply the heat power to each selected 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.

  2. Under Heat Power, do the following:
    1. Set Units to the required 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 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.
  3. To control the heat power condition by a thermostat, do the following:
    1. Click Thermostat (Transient).
    2. Click in Sensor (select a vertex) 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 enter the required value in the value box.
    4. Select the unit for the Upper bound temperature and enter the required value in the value box.
  4. Click .
