An efficient eigenvalue bounding method: CFL condition revisited
F. Xavier Trias, Xavier Álvarez-Farré, Àdel Alsalti-Baldellou +2
Direct and large-eddy simulations of turbulence are often solved using explicit temporal schemes. However, this imposes very small time-steps because the eigenvalues of the (linear…
Exploiting repeated matrix block structures for more efficient CFD on modern supercomputers
Josep Plana-Riu, F. Xavier Trias, Àdel Alsalti-Baldellou +3
Computational Fluid Dynamics (CFD) simulations are often constrained by the memory-bound nature of sparse matrix-vector operations, which eventually limits performance on modern hi…
A multigrid reduction framework for domains with symmetries
Àdel Alsalti-Baldellou, Carlo Janna, Xavier Álvarez-Farré +1
Divergence constraints are present in the governing equations of numerous physical phenomena, and they usually lead to a Poisson equation whose solution represents a bottleneck in…
On the implementation of flux limiters in algebraic frameworks
Nicolás Valle, Xavier Álvarez-Farré, Andrey Gorobets +3
The use of flux limiters is widespread within the scientific computing community to capture shock discontinuities and are of paramount importance for the temporal integration of hi…
