DESCRIPTION:Speakers: Dena Kazerani (Laboratoire Jacques-Louis Lions (UPMC
\, Paris 6))\nIn this work\, we present a numerical scheme for solving fre
e surface flows. The free surface is modeled using the level-set formulati
on. Besides\, the mesh is anisotropic and adapted at each iteration. This
adaptation allows us to obtain a precise approximation for the free- surfa
ce location. In addition\, it enables us to solve the time-discretized flu
id equation only on the fluid domain. The fluid here is considered incompr
essible. Therefore\, its motion is described by the incompressible Navier
–Stokes equation which is temporally discretized using the method of cha
racteristics and is solved at each time iteration by a first order Lagrang
e–Galerkin method. The level-set function representing the free surface
satisfies an advection equation which is also solved using the method of c
haracteristics. The algorithm is completed by some intermediate steps like
the construction of a convenient initial level-set function (redistancing
) as well as the construction of a convenient flow for the level-set advec
tion equation. Finally\, some numerical results are presented.\n\nhttps://
