A method of analysis used in situations that are difficult to model by standard engineering techniques. The finite element method operates on the assumption that any continuous function over a global domain can be approximated by a series of functions operating over a finite number of small dub-domains. The series of functions are piecewise, continuous and will approach the exact solution as the number of sub-domains approaches infinity.
                                                            
                                                     
                        
                                                
                        
                        
                            (FEA) a methodology for modeling parts using very small sections of the part geometry in a computer simulation; FEA can be used to design parts, understand how they react to deforming forces, or to simulate the flow of compound in a mold in order to optimize a molding process
