2. 1 An Example of Adaptive Mesh Refinement Let us give a simple but motivating example of adaptive computing. 4). Due to the dominant convection, some form of upwind discretization must be adopted to avoid nonphysical oscillations in the resulting m0 solution. In terms of finite element discretization, a standard technique is the so-called streamline upwind Petrov–Galerkin (SUPG) finite element formulation (see Ref. ). 2. This figure has a rectangular domain where a source term is located close to the bottom right corner of .
