Hi, hope you are doing good.
i am recently working with the SAM SSC code. i built the SAM open source using the guidelines and the code repositories given in your Github page. but when i had gone through the code files in the tcs folder, such as csp_solver_trough_collector_receiver.cpp, there are so many variables handled, but i dont know where to find the brief meanings or the definitions of those. meanwhile, can you please also tell me which change i should being upon in the code, or which segment should i refer, so that i get to understand how does SAM comes up with varying mass flow rates per hour after simulation, even though i just give only the maximum and minimum flow rates.

Regards.

Hello,

Documentation of SAM's performance model is available on the SAM website. For the "Physical Trough" parabolic trough model and other CSP models, you can find a list of publications here:  sam.nrel.gov/concentrating-solar-power/csp-publications.html

You can also find some documentation of SSC variables in the PySAM documentation, such as for the Physical Trough model here: nrel-pysam.readthedocs.io/en/main/modules/TroughPhysical.html

If you have a specific question, you might try searching the forum to find discussions that might have answers.

Best regards,
Paul.
