A large structural analysis system is developed with a view to solving challenging complex problems problems of mechanics Our subproject's objective is to develop a structural analysis system that enables us to solve multi-physics phenomena that are familiar but yet to be solved in this century.A great contribution was made to design engineering process of artifacts by structural analysis methods that are based only on a phenomenon and a single model.It is,however,not possible to simulate 100 falling leaves or flight of a hovering insect.

We first clearly declare what problems to simulate and then for a successful simulation of those phenomena,we clarify how we combine methods and how we develop an analysis system.Our efforts include but are not limited to improvement of I/O,solvers,visualization,and intelligent user interfaces.

We mean by analysis, regular analysis and inverse analysis,which is capable of giving an optimal design solution.If this system is realized,a great contribution will be made to products of manufacturing industry,
