这几天在看Perform 3D的使用说明，觉得有些话很值得借鉴。故与大家分享！
Keep in mind that the goal of structural analysis is not to get an accurate simulation of a structure's behavior, but to get information to help in making design decisions. Once an analysis model has been set up, it is easy to be seduced into believing that the model is an exact representation of the real structure. It probably is not, and it does not need to be. The model must be sufficiently accurate to provide useful design information, but the analysis results are almost certainly approximate, no matter how sophisticated the analysis model.
