| Abstract: | The problem of reducing the stencil of the local discontinuous Galerkin method applied to second‐order differential operator is discussed. Heuristic algorithms to minimize the total number of non‐zero blocks of the reduced stiffness matrix are presented and tested on a wide variety of unstructured and structured grids in 2D and 3D.
