• Gauss Quadrature Using Background Cells

In this technique, similar to FEM, Gauss points defined in a virtual mesh called background cell structure are taken as the sampling points of the integration. Therefore, integration of any given function f(x) in the system domain O can be approximated by

where is a weighting coefficient associated with the Gauss point within the cell

 

In Eq. (50), and GniwGnjw are weight coefficients of the -point Gauss integration rule [16]. Gn
