Methods and softwares for the automation of finite element analysis in 3D

摘要

During the design phase of a structure, it is often necessary to conduct several studies of the mechanical behavior whose cost in both human and computer time is often very significant. In the context of finite element computations, in order todecrease costs while respecting the user's required level of accuracy, it is essential to control discretization errors and to master calculation parameters. However, in 3D, the development of a correctly-adapted mesh presents a real difficulty. Theobjective of this paper therefore is to present a method based on several software programs in order to overcome this difficulty.
