AbstractTo make quantitative predictions of the evolution of pitting corrosion damage over time, it is necessary to develop models that properly account for possible interactions between pits. To do this, we have implemented a multiple-pit version of a previously developed algorithm for simulating the propagation of single pits in stainless steel. Propagation of each pit is assigned to a separate process and these processes can be distributed over several computers, thereby allowing multiple (coupled) pit simulations to be run in the same time as a single pit simulation. Results from many-pit simulations using this method will be presented, with a focus on the differences arising from the assumptions made about the spatial and temporal distributions of pit initiation.
