RESEARCH ON CONSTRUCTING ISOLINES AND STREAMLINES IN SEEPAGE FLOW FIELD

摘要：

Isolines and streamlines are two important tools used to analyze and visualize the flow through porous media, such as oil flow and underwater flow. Algorithms of generating isolines and streamlines based on constrained Delaunay triangulation are presented in this paper. A novel gradients calculation method is also put forward. In addition, “compass algorithm based on “wing-edge data structure is adopted to fasten the streamline integration process. Examples show the algorithms generate satisfied isolines and streamlines in domain.
