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…
On the Reynolds-number scaling of Poisson solver complexity
F. Xavier Trias, Àdel Alsalti-Baldellou, Assensi Oliva
We aim to answer the following question: is the complexity of numerically solving the Poisson equation increasing or decreasing for very large simulations of incompressible flows?…
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…
Quantifying the checkerboard problem to reduce numerical dissipation
Johannes Arend Hopman, Daniel Santos, Àdel Alsalti-Baldellou +2
This work provides a comprehensive exploration of various methods in solving incompressible flows using a projection method, and their relation to the occurrence and management of…
