FINITE ELEMENT METHOD (FINITE ELEMENT METHOD - FEM)
The Finite Element Method is a fundamental method of simulation software (Computer-aided engineering - CAE). FEM is a numerical method widely used in design analysis, prediction, and simulation problems (Simulation Technology). This method has 3 basic stages: Preprocessing, Computation, and Postprocessing. An object model after design is meshed to form elements. For specific problems, boundary conditions and materials will be applied. Then, from the input parameters, the program will arrange them into matrices. Solve the system of linear equations to obtain displacements, stresses,... Next, use interpolation methods and graphical interfaces to export the results of the problem. Engineers and users use simulation software to predict and analyze the design of models and objects, thereby optimizing and improving design quality.
