We test the efficiency of the p-adaptation strategies with unsteady two-dimensional simulations using the Euler and Navier-Stokes equations. Since the method relies on the exponential convergence of the scheme, we focus in laminar test cases. The adaptation methods enable reductions in the number ...
To achieve this, we show that a recently developed anisotropic truncation error estimator [1, A. M. Rueda-Ramírez, G. Rubio, E. Ferrer, E. Valero, Truncation error estimation in the p-anisotropic discontinuous Galerkin spectral element method, J. Sci. Comput.] is perfectly suited to be ...
The effectiveness of the method is demonstrated in the framework of unstructured-mesh finite volume discretization for two- and three-dimensional Euler flows and comparisons against several mesh adaptation approaches are shown.doi:10.1016/j.ast.2014.10.021J. Ponsin...
