[EnergyPlus_Support] Re: Internal Gains - High Consumption Equipment - Simulate

Ok, Jim,

thanks for the extremely fast reply, more information is added here:

   ** Severe  ** Temperature (low) out of bounds [-518.20] for zone="8PAV:ESTERILIZACAORAPIDA", for surface="8PAV:ESTERILIZACAORAPIDA_PARTITION_5_0_11363"

   **   ~~~   **  During Warmup & Sizing, Environment=SUMMER DESIGN DAY IN SAO PAULO, at Simulation time=01/15 20:00 - 20:01

   **   ~~~   ** Zone="8PAV:ESTERILIZACAORAPIDA", Diagnostic Details:
   **   ~~~   ** ...Internal Heat Gain [4006.000] W/m2
   **   ~~~   ** ...Infiltration/Ventilation [4.447E-003] m3/s
   **   ~~~   ** ...Mixing/Cross Mixing [0.000] m3/s
   **   ~~~   ** ...Zone is not part of HVAC controlled system.

   **  Fatal  ** CalcHeatBalanceInsideSurf: Program terminates due to preceding conditions.

   ...Summary of Errors that led to program termination:

   ..... Reference severe error count=1

   ..... Last severe error=Temperature (low) out of bounds [-518.20] for zone="8PAV:ESTERILIZACAORAPIDA", for surface="8PAV:ESTERILIZACAORAPIDA_PARTITION_5_0_11363"

   ************* Warning:  Node connection errors not checked - most system input has not been read (see previous warning).

   ************* Fatal error -- final processing.  Program exited before simulations began.  See previous error messages.

-------------------------------------------------------------------
Is the "6" of the 4006 W/m2 maybe the problem? should I indicate 3999 W/m2 for example?

Any detective hunch?

thanks.
