Preconditioning on stretched meshes
High aspect ratio cells in a computational mesh compound the inherent stiffness in the Euler and Navier-Stokes equations which arises from a disparity in the propagative speeds of convective and acoustic modes. A mesh-aligned preconditioning strategy is examined which is intended to improve multigri...
