Simulation of sedimentary basin processes using hexagonal grid representation

摘要

The invention relates to a sedimentary basin modeling method, Through the numerical simulation of the basin, at least one pore mechanics equilibrium equation is solved by using the surface smooth finite element method to determine at least one stress field and one strain field. The method according to the invention particularly comprises the following steps: subdividing the hexahedral grid represented by the grid of the basin state into at least eight hexahedral sub grids,The transfer relationship between the degree of freedom of the sub grid node and the degree of freedom of the sub grid node is determined; According to the transfer relation and the deformation displacement relation of the sub grid, the node stiffness and node force are determined.Figure 6 to be released.
