Abstract : Recent scientific studies aimed to raise the level of technical performance and the development of innovations to cope with the manpower requirements of the labor market and develop the capacity and skills of the applicants. Molecular dynamics causes a significant change in the labor market as provided by this method of simulation based on the use of numerical methods, to find solutions to the equations in atomic dimensions, to reach this information and solutions are difficult to access by traditional methods. This resulted in tremendous advances in the field of computers and programming to the great leaps consecutive and significant in several fields; specially our research. This was reflected on the development of researches and studies in various fields, especially those that rely on the study on the behavior of molecules and interaction between them, and the active nuclear powers at this level. It became possible to obtain reliable high expectations could not have been obtained previously at the level of atomic dimensions. The molecular dynamics act as a bridge between the variables at the level of atomic dimensions and those on the level of the real laboratory. The contribution to this process is cumulative and facilitates the work of researchers in this area. The goal of this research is the foundation to build a model and design a program that emulates some of the variables of interest to those working in this area where we have designed the program by FORTRAN language. This simulation begins by entering default values for sites and velocities of atoms in three dimensions of the program when implemented using these variables to calculate the new values as a function of time and then calculate the voltage, the potential energy and kinetic energy and the total energy. The main aim for this program is the calculation of the fuzzy force between atoms of molecules studied. Since fuzzy logic is one of the natural means to represent and calculate the inaccuracies in the variables and the angles of the linkage crystal lattice and therefore has been used as a way to get the approximate fuzzy forces between atoms of silicon crystal. At the conclusion of this paper present the result of simulation software, which includes: 1. Changing the position and speed of silicon crystal atoms with changing time. 2. Changing the kinetic energy and potential energy with changing time. 3. Values for the fuzzy force between silicon crystal atoms. The results we obtain are evidence for the success of this program, which can be used in any study, requires the simulation, but this program needs further development in order to be more useful for studying more complex problems in this field.
