    Testing of MH-model of Unsteady Underground Flow with Phreatic Surface

  • Original language description

    In the contribution, performed tests of model of porous media flow and their results are described, including limitations of input values. We deal with a problem of unsteady flow with phreatic surface, which is solved using MH FEM and Rothe's method. Ineach time step, non-linear problem is solved. Its solution is approximated by an iterative scheme. First, a non-linear relation describing the contact zone is analysed, aimed for setting suitable parameters. Next, tests of model problems of steady and unsteady flow are computed. In the first case, a calibration function for solving unevenness of rain dotation was set. In the second case, the relation between contact zone parameters and time and space discretization on a one-dimensional problem was tested.
