Description	V příspěvku je představena metoda adaptace sítě pro multidimensionální proudění popsané pomocí hyperbolických rovnic. Pro řešení systému rovnic je použito ADER schéma metody konečných objemů. V textu jsou porovnávány dvě metody pro lokální pohyb sítě založené na parametru kvality vrcholu s anisotropní adaptací sítě. Je představena nová strategie pro přepočet numerického řešení na nové adaptované síti. Metoda je dokumentována na problému s počáteční nespojitostí. (cs) A mesh adaptation method is proposed for multidimensional flows governed by non-stationary hyperbolic equations. The ADER higher oder finite volume method is used for the solution of inviscid compressible flow. Two different local moving mesh methods based on the evaluation of the vertex quality parameter are compared with the full anisotropic mesh adaptation technique. Anisotropic vertex quality parameter and residual vertex quality parameter are introduced. A new strategy for the recovery of the numerical solution on the newly adapted mesh is applied. Numerical results with discontinuous initial condition are presented. A mesh adaptation method is proposed for multidimensional flows governed by non-stationary hyperbolic equations.
