Solving the nonlinear and nonstationary Richards equation with two-level adaptive domain decomposition ( dd -adaptivity)

Popis výsledku v původním jazyce

Modeling the transport processes in the vadose zone, e.g. modeling contaminant transport, the effect of the soil water regime on changes in soil structure and composition, plays an important role in predicting the reactions of soil biotopes to anthropogenic activities. Water flow is governed by the quasilinear Richards equation, while the constitutive laws are typically supplied by the van Genuchten model, which can be understood as a pore size distribution function. Certain materials with dominantly uniform pore sizes (e.g. coarse-grained materials) can exhibit ranges of constitutive function values within several orders of magnitude. Numerical approximation of the Richards equation requires sequential solutions of systems of linear equations arisingfrom discretization and linearization of the problem. Typically, in the case of two- and three-dimensional problems, it is necessary to solve huge systems of linear equations to obtain only a few local updates of the solution. Since the R
