Verfahren zum Abschätzen der Beziehung zwischen der Elementenverzerrung und dem Analysefehler

A process is disclosed for estimating by a computer a relationship between geometric distortion of an element used for approximately representing the shape of an object to be analyzed by a finite element method, and an analysis error which occurs, due to the geometric distortion of the element, in analysis results of the object by the finite element method. The process includes: assuming at least one deformation mode occurring in the element upon deformation of the object, in the form of at least one of tension, bending, shear, and torsion; and estimating the analysis error associated with the geometric distortion, for each of the at least one assumed deformation mode.
