Abstract
The paper addresses Rayleigh-Taylor instability (RTI) problems and presents a method of describing an interface with markers on a Eulerian mesh, which is implemented in the MAH-3 code. The proposed method allows a more accura te description of the evolution of the interface caused by Rayleigh-Taylor perturbations and presences symmetry of the interface under appropriate sym metry of the problem (planar, cylindrical, and spherical). The method emplo ys an unstructured triangular mesh of makers. Method capabilities are demon strated on 2D and 3D Rayleigh-Taylor instability problems.
