Popis: The software PLAT, for the simulation of two-dimensional foams, has never been fully exploited, particularly in the wet limit, where it has difficulty converging. Present computer resources have enabled us to circumvent this problem. Using a data-set of 600,000 simulations, we are able to compute the polydisperse foam excess energy all the way from the dry to the wet limit. We also present data and a simple empirical function for the number distribution of n-sided bubbles for all values of the average contact number Z. Furthermore we show that, starting from a dry foam, incremental increases in liquid fraction bring with them a steadily increasing fraction f of bubbles involved in rearrangements. The size distribution of these rearrangements is found to be exponential, , where the mean, , increases in the wet limit.
