Claim Text:
1. A simulation system for simulating the operation of a process network having a set of physical plant elements through which mass flows, the process network including a plurality of process nodes including a multiplicity of junction nodes and one or more non-junction nodes that form different sub-sets of the plurality of process nodes in the process network, the system comprising: a computer device including a processor and a computer readable memory; a definition of the process network stored on the computer readable memory, the definition of the process network including the plurality of process nodes associated with the process network at which pressures or flows are to be determined in a simulation, wherein two or more of the process nodes are the junction nodes at which flow within the process network converges or diverges, and one or more of the process nodes are the non-junction nodes associated with process elements within the process network; and a simulation routine stored on the computer readable memory that executes on the processor to determine the pressures and flows at each of the plurality of process nodes of the process network during each of a multiplicity of simulation cycles, the simulation routine including:
