报告摘要：We study the contact line behavior of the threshold dynamics method we developed in the previous work. Asymptotic analysis is performed to show that one obtains correct contact angle (Young’s angle) in the leading order by choosing different Gaussian kernel variance properly. We then propose an improved threshold dynamics method for wetting dynamics. The method is based on the minimization of the weighted interface area functional over an extended domain that includes the solid phase. Each interface area is approximated by the Lyapunov functional with a different Gaussian kernel. We show that the method is unconditionally stable
