UNIFIED MATHEMATICAL MODEL IN PROCESS SIMULATION
A system simulates a process. Software instructions stored on a memory device and executable by a processor represent a process entity with a model. Instructions configure the model to function in a plurality of modes, the modes comprising a process mode, a fluid flow mode, and a dynamic mode. Additionally, instructions simulate the function of the process entity with the model in a first mode from the plurality of modes and then switch the model to a second mode from the plurality of modes.
