The source update counter is now always initialised to zero. Previously an attempt was made to determine the current number of iterations reached so that on restart the source updates occur at the same intervals as they would have had the simulation not been stopped. The problem with this is that the sources themselves are not stored to disk, so on restart a simulation could progress for quite some time before the sources were properly initialised at the next update. Resetting the counter to zero does not give a perfect restart (i.e., as if the simulation had continued without stopping), but it does provide a stable and consistent solution sequence. Perfect restart could only be achieved with this iteration procedure by writing all the sources to disk and reading them back in again. This is considered a worse compromise due to the amount of disk space that it would require. Patch contributed by Timo Niemi, VTT.
