Thermal Analysis

Th features of Watt (the thermal conduction solver) are explained here with some examples.

 

  1. The temperature distribution can be analyzed for models with temperature boundary conditions.
     

     

    In Example 1 of Thermal Analysis, steady-sate analysis is performed for metal pillars. The temperatures are set on the top and bottom faces.

     

    The temperature distribution and the heat flux are solved.

     

    In the example 2 of thermal analysis, transient analysis is performed for the same model as the example 1.

  2. Models with the heat source can be analyzed as well.
     

     

    In Example 3 of Thermal Analysis, the temperature distribution is solved for a resin cuboid. A heat source exists in its center.

     

    The temperature distribution inside the cuboid is solved.

     

    In the example 4 of thermal analysis, transient analysis is performed for the same model as the example 1.

     

     

     

     

     

     

  3. Coefficient of heat transfer can be defined as boundary condition.
     

     

    In Example 7 of Thermal Analysis, a heat source is placed on a substrate. There is a forced convection over the substrate. Heat transfer is selected as the boundary condition.

     

    The temperature distribution of he substrate is solved.

     

     

    In the example 8 of thermal analysis, transient analysis is performed for the same model as the example 7.

     

 

The functions of the thermal analysis are listed below. For more examples, see [Example List for Thermal Analysis].
