FETI-INDEED: New Perspectives in Metal Forming Simulation

INDEED is an implicit finite element code for the numerical simulation of forming processes. During the development of INDEED, emphasis has always been laid on a high prediction quality of the results with respect to some complex problems like part springback and tool stressing. To ensure a cost-effective use of such a high-end software in daily practice, the FETI method was implemented in INDEED. This method was developed for distributed memory processing. FETI-INDEED now offers new perspectives for many time consuming forming simulations such as those including deformable tools or tailored rolled blanks (TRB). FETI-INDEED even makes springback simulation become much more reliable since the use of extremely fine meshes are very often of vital importance for the quality of springback prediction.This paper, along with the oral presentation, shows a number of simulation results from different areas of application, which were obtained by using FETI-INDEED. The results not only demonstrate the excellent scalability of FETI-INDEED but are also shown to be in very good agreement with the respective single processor solutions
