Node Limit In Cosmos/Works 2008 SP3.1 on Windows XP64

I seem to be having problems with large problems over 1million nodes. If I have more that 1 million nodes the results seemcompletely erroneous or does not solve but when I coarsen the meshthe results look reasonable. Does anyone know if S/W has qualifiedthis service pack for meshes larger than 1 million nodes. SinceCosmos/M does not have solvers for over 1 million nodes I can'texport and try it with Comsos/M.SolidworksSimulation
