Three dimensional analytic model generation method, device, three dimensional analytic model generator program and its record media

摘要

According to a 3-dimensional analysis model forming method, a 3-dimensional detailed model constructed by a plurality of parts is inputted, the 3-dimensional detailed model is simplified into a shape suitable for layout and it is converted into a first approximate model (3-dimensional patch approximate model). Further and the first approximate model is converted into a second approximate model (approximate model for analysis) simplified into a shape suitable for analysis by an analysis PROGRAM and inputted into the analysis PROGRAM.
