“…The main purpose of this chapter is to give a basic introduction to these functions, briefly explain some of the underlying theory, and give several code-centric examples of how the functionality in the module can be used to generate complex grids that conform to geological objects and well paths. For a more comprehensive overview of alternative methods and previous research, the reader can consult [2,6,8,[13][14][15]18]. We emphasize that the upr module is a research tool for constrained gridding and not a robust industry-grade geomodeling tool.…”

A fractured poroelastic body is considered where the opening of the fractures is governed by a nonpenetration law while slip is described by a Coulomb-type friction law. This physical model results in a nonlinear variational inequality problem. The variational inequality is rewritten as a complementary function, and a semismooth Newton method is used to solve the system of equations. For the discretization, we use a hybrid scheme where the displacements are given in terms of degrees of freedom per element, and an additional Lagrange multiplier representing the traction is added on the fracture faces. The novelty of our method comes from combining the Lagrange multiplier from the hybrid scheme with a finite volume discretization of the poroelastic Biot equation, which allows us to directly impose the inequality constraints on each subface. The convergence of the method is studied for several challenging geometries in 2d and 3d, showing that the convergence rates of the finite volume scheme do not deteriorate when it is coupled to the Lagrange multipliers. Our method is especially attractive for the poroelastic problem because it allows for a straightforward coupling between the matrix deformation, contact conditions, and fluid pressure.
