  • Modeling continuous properties on discontinuous surfaces
    Patent number: 6820043
    Abstract: A method of establishing continuity of a property which is interpolated over a surface defined by at least two primary nodes. The method includes identifying first and second portions of a boundary which defines a discontinuity in the surface. The method further includes defining the first and second portions of the boundary by at least one secondary node on each portion, and interpolating the property from a first primary node to a second primary node by utilizing the secondary nodes. When the property is characterized by determined values at primary nodes on the surface, the continuity of the property can be established as substantially the same value of the property at the selected secondary nodes. When the surface is characterized by a given gradient at each of the secondary nodes, the continuity of the property can be established as substantially the same gradient at the selected secondary nodes.
