Abstract :
Application of a finite difference front fixing method to various problems with moving boundaries and nonlinear material properties is discussed. Advantages and implementation problems of the method are highlighted. Particular attention is given to conservation properties of the algorithm and accurate solutions close to the moving boundaries. The algorithm is tested using a well-known solution of the plane diffusion problem with complex conditions at the moving interface.
