Features:

The user inputs the sink width, height and thickness.

A sink material can be selected from Aluminum, Copper, FR4, Steel or Silicon.

An airflow velocity and ambient temperature are input.

Set up grid is done that can be interacted with for heat loads and finned areas.

Heat sources and finned areas can be mouse draw on the sink.

Heat source heat loads, W, are input. The fin details are input.

Stead-state and transient solution options are available.

For the transient case the final step is temperature contour plotted on the sink surface and a T(t) plot given.

Mouse clicking on the contour plot enables the user to see specific location and temperature.

The results can be exported.
