WebThe 1D heat equation is a partial differential equation that describes the flow of heat in a one-dimensional medium. It states that the rate of change of temperature at any point in the medium with respect to time is proportional to the second derivative of temperature with respect to space at that point. Mathematically, it can be written as:
WebAs indicated a(u) has to be approximated at the indices (j + 1 / 2) and (j − 1 / 2). This may simply be done by averaging the neighbouring values: aj + 1 / 2 = 1 2(un j + un j + 1) for the burger equation. Another method that assure conservation is to use the following approximation aj + 1 / 2 = {Fn j + 1 − Fn j un j + 1 − un j if uj + 1 ...
