METHOD AND SYSTEM FOR SOLVING FINITE ELEMENT MODELS USING MULTI-PHASE PHYSICS

机译:多相物理求解有限元模型的方法和系统

摘要

Systems and methods for solving finite element models, wherein the matrix thatgoverns the solution is modified by adjusting the weighting coefficients ofthe matrix so that the elements which lie on the diagonal of the matrix arenon-negative and the elements which are off the diagonal are non-positive. Inone embodiment, a system is discretized on a finite element mesh with thecontribution of each node to the discretization being weighted based upon thedirection of fluid flow across each element. The nodes which are upstream fromthe other nodes of the respective elements are weighted more heavily to causethe resulting matrix to be substantially diagonal. This matrix is solved usingtraditional techniques.
