WebIn order to give the numerical analysis and simulation of the collapsing of a sandpile, we give, in this paper, a more precise description of I Q, in terms of a composition of WebPreviously, these problems were solved for the special case in which the inequality is simply variational. Here, we introduce a regularized mixed formulation involving both the primal (sand surface) and dual (sand flux) variables. We derive, analyse and compare two methods for the approximation, and numerical solution, of this mixed problem.
