Heat Transfer Rate (Q)
Keep the following points in mind when you specify the heat transfer rate on the Heat Load dialog box. For a curve, surface, beam, shell, solid, 2D plate, 2D shell, 2D solid, edge, or face:
The heat transfer rate is a total or distributed heat transfer rate, depending on the distribution option you selected. You can enter any real number.
If you define interpolation points and add scale factors before you specify a load value, Creo Simulate assumes a default value of 1.
The number of interpolation points you select determines the functional form of the interpolation.
For all entities, when you are specifying the heat transfer rate:
To make the loaded entity a heat source for the model, enter a positive value for Q, which adds heat to the model.
To make the loaded entity a heat sink for the model, enter a negative Q value, which removes heat from the model.
Creo Simulate displays the signed value of Q with the heat load icon.
