摘要

We study a Lagrange multiplier based non-overlapping domain decomposition method for the nonlinear over-pressure equation. Using an additional unknown, the problem is restated as a linearly constrained minimization problem. The resulting Uzawa-type algorithm requires at each iteration the solution of one uncoupled Poisson problem.
