Different Results from FloSimulation09 than FloWorks07

Having recently upgraded to SoildWorks09 with a FloSimulationAdd-in, I have been running some older projects again to getfamiliar with how things have changed.

If I just re-run the simulation, with the same FloSimulationProject, I get ridiculously low temperature outcomes e.g max tempsof 20.6 where there were 60.9 degrees C.

Making a new FloSimulation Project with exactly the same goals,gives 59.7 degrees C rather than 60.9 degrees C maximum.

Has anyone else experienced this?SolidworksFlow Simulation
