This paper deals with the description of a new numerical simulation technique based in the constrained natural element method, a novel meshless method, able to compute multiphase thermal problems with moving interfaces without requiring the frequent mesh updating characteristics of interfaces tracking finite element techniques. This strategy combines some of the ideas of the natural element method with a particular treatment of the moving boundaries and interfaces involving dis-continuities of some fields.
