Example3 Block Containing Heating Element(Steady-State Analysis)

General

  • A heating element is placed in a block. The ambient temperature is constant.
     

  • The temperature distribution and the heat flux vectors are solved.
     

  • Unless specified in the list below, the default conditions will be applied.

Results

A section’s temperature distribution is shown below.

The hottest point is the center of the heating element. The temperature is 266[deg].

 

Shown below is the isosurface contour of the temperature distribution. “Shading” and “Translucency” are enabled.

The 3D temperature gradient is exhibited clearly around the heating element.
