In this paper we present and analyze results of
numerical simulation of propagation and interaction of free
boundaries in the modified Stefan problem. With the viewpoint of
the theory of distributions, we consider singularities of
(H,x+)
type, where H is the Heaviside function and
x+=xH(x) .
Key words:
modified Stefan problem, phase field, kink,
interaction, free boundary
