Discrete weighted Galerkin formulation

The most important full CLD methods are the extended methods of moments, such as the probabihty generating function method and coarse-graining-based techniques the fixed pivot method and the discrete weighted Galerkin formulation. In what follows, the most important aspects of these methods are highlighted. 

In the discrete weighted Galerkin formulation, the CLD is represented by an expansion in basis functions until a truncated value (A/tr) (Budde and Wulkow, 1991 ledema et al., 2003 Wulkow, 1996). For example, for the dead polymer this implies that the CLD at time t is... 

Felicelli et al. [54] used a bilinear Lagrangian isoparametric element to discretize the transport equations. The convective terms are dealt with using a Petrov-Galerkin formulation in which the weighting function is perturbed in the convective term. The perturbed weighting function is expressed as ...
