Emergence property is an idea that population of local agents which obey simple rules of behavior emerges a complex global structure which is not predictable from the rules. Nowadays a number of phenomena in the filed of physics, chemistry, biology, physiology, sociology and information technology are perceived as results of emergence property. In the context of engineering design, emergence property is often referred to a concept of design synthesis. The authors reported an application of emergence property to mechanical analysis of elastic bodies in 2004. In the report we adopted cellar automaton as simulation framework and showed that structural analysis was realized without any global system equations solved. Analysis methods which require a global matrix, such like FEM, FDM, FVM, BEM and so on were not used in the process and purely local calculation emerged global state of stress, strain and deformation of the elastic bodies. In the subsequent report, we also showed an application of topology generation of structure. However, the set of local rules we used has high complexity therefore it inhibited application of proposed algorithm to complex real-world structures. In this report we present a concept of new formulation of the local rules, which aim to apply proposed rules to analysis of real world structures and morphogenesis.
