Andrés Rueda (ESR1) collaborates with Prof. David Kopriva during his secondment at San Diego State University
Andrés Rueda (ESR1 from UPM) completed his secondment at San Diego State University, United States where he joined the research team of Prof. David Kopriva and Prof. Gustaaf Jacobs in the Department of Aerospace Engineering and Engineering Mechanics. The common research was focused on the development of a time-implicit Discontinuous Galerkin Spectral Element Solver (DGSEM). The main goal of the research work was to derive the analytical Jacobian matrices for the compressible Euler and Navier-Stokes equations, and to test different time-integration schemes and solvers. During the fruitful collaboration, preconditioned Newton-Krylov algorithms and multigrid solvers were assessed, and the effect of p-nonconformities on the mesh representations of the DGSEM was investigated.
