جواب معادله پواسون غیر خطی با شرایط مرزی مخلوط به روش اجزاء محدود

Abstract

In this paper a method is presented in details to solve a nonlinear partial differential equation which has many applications in engineering fields. The boundary condition is mixed to be able to define the value of function on its variation on the boundary. Examples are given to demonstrate the accuracy and efficiency of the method.
