Claim 0:
1. A non-transitory computer-readable medium storing instructions, which when executed by one or more processors of a system, causes the system to perform a method, comprising:
receiving 3D data representing a vessel segment of a vasculature;
determining a 0D model of the vessel segment based on static fluid simulations of the vessel segment using the 3D data, wherein the 0D model includes a respective inductor and a respective pressure source for each of a plurality of subsegments extending between an inlet and a plurality of outlets of the vessel segment, and wherein values of the pressure sources are taken from a response surface of the static fluid simulations of the vessel segment;
generating a set of boundary conditions of the vessel segment based on a first vascular system model including the 0D model of the vessel segment coupled to a 0D model of a remainder of the vasculature; and
generating a reduced order model of the vessel segment based on transient fluid simulations of the vessel segment using the set of boundary conditions, wherein the reduced order model represents flow in the vessel segment in real-time.
