Abstract
This study deals with a class of variable coefficients second-order parabolic moving boundary problems. The evolution of the domain is considered to be an unknown function. Based on the front-fixing approach, first, the problem is derived as a nonlinear fixed domain parabolic problem, and the uniqueness of solution of this problem is shown. An iterative approach based on a backward finite difference method is proposed to solve this nonlinear problem. The solvability of the finite difference method is shown, and the stability and convergence of the numerical solution are proved. Two examples are considered to show the efficiency and compatibility of the numerical method.
