报告简介：

In this talk, I will discuss parametric approximations for axisymmetric geometric evolution equations. We consider two different possible approximations of the curvature, which leads to either an unconditional stability or an asymptotic equal mesh distribution. An exact volume preservation for the discrete solutions can be further strengthened with an appropriate suitable approximation to a combined term of the radial distance and the interface normal. Moreover, we generalize the parametric approximations to the two-phase flow, where the interface evolution is influenced by the bulk quantity. We propose several front-tracking approximations which combines the parametric finite element method for the interface equations with the standard finite element methods for the bulk equations.
