Calculating gravity stress and unit measuring-points stress in a FEM model of practical engineering.
All three axis origins in calculation are (3713600 m, 39424800 m, -410m) different from the engineering coordinate origin.

So the operation is more complex, and the error rate is higher in the engineering analysis.
Introduction CAE is a rapid development of information technology, is an engineering software to achieve the engineering and product analysis, simulation, design and manufacturing processes optimization; it is the more important tools and means to support engineers to carry out innovative design, but also one of the important means of science and technology research.
As there are no industry-level systems for support of non-algorithmic tasks of FEM-based engineering analysis, such tasks are carried out by engineers on the basis of expert knowledge and experience.
