A software plant process modeling system creates a process flowsheet model. The software system creates at least a first unit model as part of the process flowsheet model. The software system displays at least one equation in the first unit model. The software system permits a user to display at least one equation in the first unit model. The software system further permits the user to modify the first unit model. The software system generates an open-equation model to solve the process flowsheet. Thus, a user may interactively create, modify, and solve a process flowsheet model in open-form.

1. A method for creating a process flowsheet model representative of a physical process effected by one or more devices, said method comprising:instantiating an instance of a first unit model as part of said flowsheet model, said first unit model being representative of at least one or more physical aspects of operation of a first device; displaying at least one predefined model equation associated with said first unit model in response to a user command, said at least one predefined model equation including a parameter indicative of a measured value of at least one of said physical aspects; receiving a user modification of said at least one equation; and determining a solvability state of said flowsheet model in open-equation form.
