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!
