I got my RDD from simulation using Conduction Finite Difference solution algorithm and it is showing several output variable for example "Output:Variable,*,CondFD Phase Change State 1". 
 
Based on the EnergyPlus Input Output Reference the number "1" is indicating the nodes in the surface. 
 
How can I know which layer of the surface that the node representing for? the RDD files showing node from 1-18.
 
Thank you!

The EnergyPlus I/O Reference has the following documentation for some of the CondFD Phase Change inputs (like this one):
 
 
The nodes are numbered from outside to
  inside of the surface. The full
  listing will appear in the RDD file.

Thank you for answering. However in my RDD file, it is showing 18 nodes. So, which number of node is representing that specific surface that use the Conduction Finite Difference algorithm?

Have you seen the Engineering Reference description on how the nodes are determined? See here.
