Has anyone ever had a 1D/2D model run for a long period of time and then suddenly go unstable without any results being written to the 1D *.O## output files? The *.hdf file for the associate plan contains data just prior to it going unstable. In my case the model simply says that the 2D Solution went unstable at 27MAR2010 02:23:58 but it also says that the simulation went unstable at 11MAR2010 23:58:39 which is during the warmup period. How can a model go unstable in the warmup period and still continue to process only to go unstable again?
Aside from the sudden instability the model was running rather stable.
