Non Linear Thermal Analysis

In the hypothesis of non stationary heat transfer phenomenon, such as the study of the thermic field transient influenced by the temporal modification of the contour conditions, a finite element research needs to be faced by using codes which consent the gathering of the heat transfer dynamic effects.

Such situations are typical of motors in the heating phase, or in the phase of ignition and extinction of a cooling system. Even electronic circuits present in certain thermic transient situations need to be considered by the designer to be able to avoid an excessive heating of the components. Another sector which takes advantage of the same approach is the calculation evaluation of the cooling process of the pouring of metal inside a mold, in order to guarantee the correct production of the piece.

There are other situations in which the thermic exchange coupled between fluids and solids, or between fluids of different circuits, as for example in a heat exchanger, can be cought in their complexity only through a non linear approach.
