Python scriptsto compute temperature increase of nanowire/substrate using analytical approximation (as described here). Contents DownloadA zip and gzipped tar is available for download. Sample outputPlotsThe script that can be downloaded will produce the lines labelled "analytical approx" in the plots shown below. The comparison with the FEM data for particular studies from the publication can be de-activated, and material parameters and geometry can be varied. The README.txt gives more details, and there are guiding comments in the source code.

Data filesThe scripts do also write the data into text files such as T_3d_substrate.txt and T_2d_substrate.txt where the first columns represents the time (in seconds) and the second column the maximum temperature of the substrate (which is likely to be the minimum temperature of the wire). Files that contain 3d refer to a three-dimensional substrate (i.e. substrate much thicker than length of wire) and names with 2d refer to a two-dimensional substrate (i.e. substrate much thinner than length of wire -- typical for membranes). Software requirementsAre detailed in the README.txt file. In short, you need Python and numpy, and -- for plotting -- matplotlib. README.txtIncluded in the downloadable archive (or here: README.txt).
