Some aspects of artificial diffusion in flow analysis
article
A recent artificial diffusion method is briefly discussed. The method is illustrated in one and two dimensional convection diffusion problems. It is also used in an incompressible flow problem (Poiseuille flow). The incompressibility condition is imposed both weakly (weighted formulation) and with a discrete penalty formulation results are compared for the Poiseuille flow. Some preliminary considerations on fluid-structure interaction are given. Finally, the question of whether to use direct or iterative solvers in flow problems is addressed.
