An algorithm for dynamic simulation of chemical engineering systems, using the sequential modular approach, is proposed. The modules are independent simulators, and are integrated over a common time horizon. Interpolation polynomials are used to approximate input variables. These input polynomials are updated before modules are integrated in order to interpolate output from the preceding module(s) and thereby increase coupling and stabilize the computation. Tear-stream variables have to be predicted at future time tn+1, and various prediction methods are proposed. © 1986.
