Study of rapid modeling of automotive frame based on CAE

This paper discusses the energy-based One-step release of initial field indicates solver algorithm. Finite element for solving large-scale linear sparse matrix direct methods and iterative methods were also conducted in-depth study and research. On the One-step treatment system before and after a number of key algorithms have been studied, including pre-processing finite element mesh polygon selection algorithm and finite element mesh quality and discounted content identification and correction algorithms. On KMAS / One-step solver automated test environment to study and design and implementation of the relevant test procedures.
