21. The latter would result in an intractable problem, hence the utility of the finite element method . 22. More complex problems can be solved by the finite element method or space-time finite element method. 23. Traditional finite element method is a well-established method to solve various problems of science and engineering. 24. A typical such a formulation is the so-called smoothed finite element method ( or S-FEM ). 25. For example, a mixed finite element method applied to conserves the mass of the flowing fluid. 26. It can also calculate displacement using the finite element method to determine stresses throughout the part. 27. More complex problems can be solved by the finite element method or space-time finite element method . 28. These tools established finite element methods as a new reference point for believable on-screen destruction ." 29. Wendroff has also made contribution to the early development of convergence study of finite element method . 30. Finite element methods base on balancing the forces on a differential volume element and calculating its response.
