Systems and methods for predicting a plurality of thermodynamic states of a plurality of heat, ventilation, and air conditioning (HVAC) devices of an energy plant are disclosed. The system includes a processor and a non-transitory computer readable medium storing instructions when executed causing the processor to: obtain plant netlist data describing the plurality of HVAC devices of the energy plant and connections of the plurality of HVAC devices to corresponding nodes; identify, from the plurality of thermodynamic states of the energy plant at a plurality of nodes, a reduced subset of the plurality of thermodynamic states to be predicted based on the connections of the plurality of HVAC devices; predict the reduced subset of the plurality of thermodynamic states using a non-linear solver; and determine the plurality of thermodynamic states of the energy plant based on the reduced subset of the predicted thermodynamic states.
