**1. Introduction**

"To move precisely in nanoworld, you donot succeed by perfecting proven techniques".- Handelsblat. [1] . As stated, the nano research requires newer methodologies and techniques to be worked out to succeed. The microtechnology to nanotechnology needs a factor of thousand for size reduction. Different methodologies exist to club cooperation between macro, micro and nano robots and analytical based FEM for static, modal, harmonic and transient analysis of structures. Clubbed with multiparametric optimization and neural networks, FEM had developed as an optimal solution to all complicated problems of engineering, science, technology, medicine and research. The **"**bottom up" technology of late twentieth century promises the use of robotics for micro/nano manipulation processing [1]. The revolution of computers had led to development of closed form solutions which are extremely difficult to be obtained for any engineering problems [2]. This urge leads to adopting any one of the numerical techniques. FEA had been one of the options of researchers and choice of the method depends on the familiarity of the users. FEM exploits the research methodologies using direct approach, variational approach, direct approach, energy approach, weighted residual approach, Isoparametric formulation, static condensation and nonlinear analysis [2]. Numerical approximations can be reached by differential equations and PDE for various mathematical and nano technology problems of applied physics. FEM explores checking the validity of analytical studies of

nanotechnology. Moreover the unaffordable experimental setup of nanoresearch could be replaced with FEA software as observed by engineers and scientists working on the field [2].
