A heating element is placed in the center of the 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 will vary depending on Femtet version and the PC environment.

A cross 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.
