I am using Meshless Petrov-Galerkin Method(MLPG) for non-rectangular domains. There is a flexibility of using any shape for weight function and also for local quadrature  domain. Here in my case case weight function domain and local quadrature domains are same.

 I want to know that  , for non-rectangular domains,how the different shapes of weight functions (specially circular or rectangular) will affect accuracy of the result  ?

I have finished building the transfer function model of mechanic systems in MATLAB.  But now if I am going to write the model in C language, what could I do? Any hints, fire are welcome!

Abstract of paper recently accepted for publication in Journal of Applied Physics:

It is generally believed that similar to soluble ligand-induced signal transduction, mechanotransduction initiates at the local force-membrane interface (e.g., at focal adhesions) by inducing local conformational changes or unfolding of membrane-bound proteins, followed by a cascade of diffusion-based or translocation-based signaling in the cytoplasm. However, all published reports, including past studies with the reporter type of construct extended here, were limited in timescale to address this fundamental issue.

Xin-Lin Gao and I had the pleasure of guest-editing a special  issue on "scale effects in mechanics" for the journal, Mathematics and Mechanics of Solids (editor: Professor David Steigmann , UC Berkeley).
