Abstract

The reliability and usefulness of the numerical simulations of a physical process depend not only on the mathematical model representing the process, normally in forms of differential equations, but also on the accuracy and efficiency of the numerical methods for solving such equations. This paper presents the theoretical basics of a new numerical method, namely Meshless Level Set method, in which the advantageous features of meshless methods and level set methods are integrated to solve moving boundary problems. Some benchmark problems solved by the method are presented to demonstrate the accuracyand efficiency of the method as well as its potential applications in petroleum engineering.
