Verfolgung fluiddynamischer Diskontinuitaeten mittels Level-Funktion

The present level-set-algorithm describes a front-tracking method to calculate discontinuities of fluiddynamic problems as shocks, detonations or material-discontinuities as bubbles on arbitrary grids.Beside the description of the classical local-level-set algorithm an extension is presented to overcome restrictions of this classical method. An evaluation of the accuracy of this method is done in the combination with the caculated examples as bow-shocks in a 2D and 3D frame, 2D detonation, zonal-solution and two phase-flow computations.
