Discrete weighted Galerkin method

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.

The unknown field quantity w, the test function, and all required derivatives of these quantities can be decomposed into contributions of the n elements following from the discretization of the system. By means of weighted basis functions (also denoted as ansatz functions) the following approximation is derived (Galerkin method) ...
