[EnergyPlus_Support] Re: RunSlab Program
Hi,
I have run the idf using the regular EP-Launch and I got the following severe error message:
----------------------------------------------------------------------
** Severe ** Output:PreprocessorMessage="GroundTempCalc - Slab" has the following Severe condition:
** ~~~ ** The calculated ground temperature exceeds -100 C [-104.07 C]
----------------------------------------------------------------------
The idf has the complete set up of the building model and it runs fine before setting the GroundHeatTransfer objects.
Does anyone know the cause of this error?
Thanks.
