Abstract:
1. A computer implemented method to model a propulsion-related interface, the method comprising computer-implemented operations for: receiving, at a modeling system, a model comprising mathematical expressions for representing a structure comprising the propulsion-related interface; calculating values for conditions adjacent to the propulsion-related interface; determining if flow directions associated with the values are oriented in a same flow direction; in response to determining that the flow directions associated with the values are oriented in the same flow direction, computing a mass flow rate at the propulsion-related interface, computing a jump in conserved variable state associated with the propulsion-related interface based, at least partially, upon the mass flow rate, and computing a jump in flux across the propulsion-related interface based, at least partially, upon the mass flow rate and the jump in conserved variable state; in response to determining that the flow directions associated with the values are not oriented in the same flow direction, indicating no losses across the propulsion-related interface; embedding the values in the model; and solving the model to compute a solution associated with the model.
