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.
