Abstract: Describes the concept of invere solution in CAE and it theoretical basis,presents a new approach for the inverse solution of loading though a combination of FEM-BEM and experimentation and also a new algorithm for the solution of morbidequations.It's application on the analysis of pressure in an extiaction die gives arelative error of only less than 8% between the experimental and computed data, thus abasic problem in this kind of CAE is solved.
