Identifying Cell Positions in a HAMT Wall in EnergyPlus

edit

Hello everyone,

I’m a building physics researcher currently using the HAMT model in EnergyPlus to simulate a guarded hot box for comparison with experimental measurements.

In my simulation, I’m retrieving the following outputs:

Surface Inside Face Temperature Surface Outside Face Temperature HAMT Surface Inside Face Temperature HAMT Surface Outside Face Temperature HAMT Surface Temperature Cell 1 to 22

These values come from the wall surface named:

BCG:CHAUD_PARTITION_4_0_10002

In order to validate my model, I need to align the simulated temperatures with temperature sensors embedded at different depths in the physical wall. To do this, I need to understand the exact position of each internal HAMT cell.

Specifically: Does Cell 1 correspond to the inside or the outside surface? Are the 22 cells distributed evenly across the wall thickness, or do they follow a specific distribution (e.g., geometric)? How can I retrieve or reconstruct the position of each cell in the wall layer? Is this information available in the IDF file or any output files?

Any help or documentation references would be greatly appreciated.
