[EnergyPlus_Support] Re: Finite difference method error

Jose,

I have tried many timestep regimes, including the min and max allowable.

I have run the sim for a year, and it still doesn't reach good results.

I didn't try changing the number of control volumes, but I am not using massive materials.  Just the default exterior wall construction.

However, I'm seeing a difference of about 3C between the two zones throughout the day.  The zones remain within ~0.2C using the ConductionTransferFunction method.  Thoughts?
