[EnergyPlus_Support] ground temp calculation

["hbn_pch" <hbn_pch@xxxxxxxxxxxx>]

Hi,all
    When we use the slab.exe utility to calculate the ground temp,we 
can start with a copy of the example file 
EnergyPlus\PreProcess\GrndTempCalc\SlabExample.idf. But at a minimum, 
the thermal properties and area-perimeter ratios must be changed to 
match the slab you are simulating in EnergyPlus.I have some doubts for 
the change:
 1.Which object in the idd description correspond the thermal 
properties?That is which object should i change.

 2.How to set the area-perimeter ratios?Is there some rules or some 
standard?

 Thanks.
  
 pch
