Abstract One of the most commonly used methods in numerical solution of partial differential equations is the finite element method. In the finite element method, the region to be analyzed is divided into sub-sections called solution regions provided that the boundaries of the region are determined. This subdivision method depends on the type of differential equation to be solved. A variety of solution network production techniques are used to subdivide the solution region. By selecting the appropriate method, the solution region is divided into sub-compartments to ensure that the solution is faster and more accurate. The classical finite element method gives accurate results when instant analysis is performed on the solution area. However, in cases where partial differential equations change with time and solution network changes regionally, it is useful to use moving finite element method instead of classical finite element method. The use of a moving finite element method allows analysis to be carried out only in varying regions of the solution network to ensure rapid results. In this study, two dimensional solution network production techniques are mentioned. With the help of the developed program, regional changes on the solution network are explained in detail. As an application, C ++ based software was implemented.
