Claim 12:
13. A non-transitory computer-readable medium storing instructions, which when executed by one or more processors of a system, cause 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;
receiving measured flow data representing measurements of flow in the vessel segment;
generating simulated flow data representing flow in the vessel segment based on a first vascular system model including a reduced order model of the vessel segment coupled to a 0D model of a remainder of the vasculature, wherein the reduced order model represents flow in the vessel segment in real-time, and wherein the reduced order model is based on the 0D model of the vessel segment; and
adjusting the 0D model of the remainder of the vasculature based on a comparison of the simulated flow data to the measured flow data.
