Formaggia, Luca; Villa, Andrea
In this work a new coupled level set - volume tracking method is introduced. To advance the solution in time, a MUSCL-type method combined to a new °ux limiter is used. It is shown that our discrete method has many interesting properties that make it suitable for problems where the tracking of a large number of regions is needed. A dedicated reconstruction algorithm for the level set reinizialization is also provided. We show some numerical tests demonstrating its effectiveness for multi-°uid problems.
