Abbas Khayyer,Hitoshi Gotoh +1 more
TL;DR: In this paper, the authors presented particle-based simulations of a dam break on a wet bed by standard and improved versions of three particle methods, namely moving particle semi-implicit (MPS), incompressible smoothed particle hydrodynamics (ISPH) and weakly compressible smoothed particle hyddynamic (WCSPH), with a moving least square density re-initialization.

Volume of fluid (VOF) method for the dynamics of free boundaries
C.W Hirt,B. D. Nichols +1 more
TL;DR: In this paper, the concept of a fractional volume of fluid (VOF) has been used to approximate free boundaries in finite-difference numerical simulations, which is shown to be more flexible and efficient than other methods for treating complicated free boundary configurations.
