Recently FEM is trying to be used as much as possible as the central technique of CAE in design and manufacturing processes. It has been already recognized among manufactures that shortening development period depends on whether we can use as much analyzing texhnique as possible or not. The theme related to quality of computation is getting into the big news. This is considered to be caused by the hope that computation comes to be the substitution for the experiment because of the progress of simulation mechanics and hardware. On the other hand, however, this can be considered as the reflection because lack of calculating computation keeps analysis from fixing. And thirdly, there are three categories for the quality of FEM ; that of FEM of its own, that of calculating technique, and that of modeling for the phenomena. But it is still thought that there is lack of clear analysis because researchers don't build up a clear connection with one another. So here, I mainly explain the problems related to modeling, especially in practical viewpoint, and I also explain about the quality of FEM of its own, and that of calculating technique, because these three are closely related with each other.
