I am simulating an EnergyPlus model with PhaseChangeHysteresis object. 
 
Based on the RDD file it says that I can report  "CondFD Surface Temperature Node" for nodes 1 to 29. However, for a specified exterior wall (which include PCM), the output table reports nodes 1 to 20 and not 29. other surfaces like a ceiling, (without PCM) it shows all temperature nodes from 1 to 29. I appreciate any help.

The number of nodes that are reported for each construction depends on the thermal diffusivity of the materials (α) used in the same and I assume not all of your constructions will be the same. If you read out the variables with higher node numbers for all surfaces (please note that I refer to model planes as "surfaces" here, and not the surface of a construction itself), you will see which ones are divided into more elements.

Thank you for your response! I have seen two walls beloning to the same construction (exterior walls) one with only one node and the other is with 20 nodes.
