1. A method for determining flow control device settings, comprising:
obtaining data representing flow rates for a plurality of flow control devices;
determining total molar rates for a plurality of flows through pipe segments associated with the flow control devices based on the obtained data;
determining initial flow control device constraints based on the total molar rates for the plurality of flow control devices;
sorting the initial flow control device constraints such that a smallest of the total molar rates is a highest ranked of the initial flow control device constraints;
determining that one or more wellhead constraints would be violated based on the initial flow control device constraints;
determining adjusted flow control device constraints that result in the satisfaction of the one or more wellhead constraints or constraints of others of the plurality of flow control devices;
determining an adjusted flow rate based on the adjusted flow control device constraints, wherein the adjusted flow rate corresponds to the highest ranked of the initial flow control device constraints; and
executing a computer-based instruction to set one or more wellhead settings and flow control device valve settings based on the adjusted flow control device constraints.
