    Discrete Maximum Principle for a 1D Problem with Piecewise-Constant Coefficients Solved by hp-FEM

  • Original language description

    In this paper we prove the discrete maximum principle for a one-dimensional equation of the form - (au´)´= f with piecewise-constant coefficient a(x), discretized by the hp-FEM. The discrete problem is transformed in such a way that the discontinuity ofthe coefficient a (x) disappears. Existing results are then applied to obtain a condition on the mesh which guarantees the satisfaction of the discrete maximum principle. Both Dirichlet and mixed Dirichlet-Neumann boundary conditions are discussed.

    Diskrétní princip maxima, pro 1D úlohu s po částech konstantními koeficienty řešenou hp-verzí metody konečných prvků

  • Czech description

    V tomto článku dokazujeme diskrétní princip maxima pro jednorozměrnou rovnici ve tvaru -(au´)´= f s po částech konstantním koeficientem a(x) diskretizovaným hp-verzí metody konečných prvků. Diskrétní úloha se transformuje takovým způsobem, že nespojitostkoeficientu a(x) zmizí. Potom se aplikuje známý výsledek pro Poissonovu rovnici a obdrží se podmínky, které zaručují splnění diskrétního principu maxima. Oboje Dirichletovy i Neumannovy okrajové podmínky jsou studovány.
