MODELING SUBSURFACE PROCESSES ON UNSTRUCTURED GRID |
摘要 |
<p>Embodiments of the invention involve forming a prismatic grid and solving a convection-diffusion problem using the prismatic grid and mixed finite element analysis. The prismatic grid may be formed by providing a triangular mesh on a plane of a model. The mesh is then coarsened to make cells that are less desirable larger. The coarsened grid is then projected to form the prismatic grid. Each cell of the grid is then assigned a plurality of degrees of freedom. Mixed finite element analysis of the grid produces a matrix, which is then solved to yield a solution to the convention-diffusion problem.</p> |
