Patent ID: 7308391

Claim:
A method of producing a triangulated surface representation of flow data at a selected portion of a gravity hydraulic network comprising the steps of: (A) generating at least three matrices of values, including one for headwater, tailwater and flow for a selected portion of the hydraulic network; (B) plotting tailwater values on an x-axis versus headwater values on a y-axis as data points to produce data rectangles in a tailwater-headwater plane; (C) adding additional data points by splitting each data rectangle into a plurality of subrectangles and dividing the subrectangles into triangles; and (D) calculating and storing, in a doubly indexed array of integers, tailwater and headwater values for given values of flow, while preserving the condition that flow is zero when tailwater equals headwater; and (E) plotting each flow value on a z-axis for each triangle for producing a triangulated surface representation of the flow data in three dimensional space.
