Abstract
A method for generating a mesh of a subterranean medium comprising at least one sedimentary layer crossed by at least one fault. The at least one layer is delimited vertically by two geological horizons discretized by two triangulated three-dimensional surfaces. For each horizon, a three-dimensional gridded surface is constructed by means of isometric unfolding accounting for the presence of the fault. Next, the mesh of the subterranean medium is generated by generating cells by creating links between the three-dimensional gridded surfaces. To do this, nodes of the first gridded surface that are situated on one side of the fault which differs from the side of a node of the second gridded surface having the same coordinates i, j are detected. Each non-detected node is joined with a node of the second gridded surface having the same coordinates i, j, and each detected node is joined with the fault by considering a direction of a neighboring node. Finally, the cells having at least two vertices in common are regularized.
