Resumen:
The main target of this lecture is to look for algorithms to simulate
CFD problems as fast as possible, improving the current performance of
general-purpose commercial codes. This goal does not mean yet obtaining
Real Time CFD solution but this goal is on this way, with the aim of
changing days of simulations for hours of simulations making feasible
the present challenging demands of engineering design.
Even though implicit time integration schemes are preferred in the
literature against explicit ones, the latter are in a better position
attending to the present of hardware technology that is oriented to the
usage of general purpose graphic processor units (GPGPU).
On the other hand it is not obvious that an Eulerian approach is better
in terms of efficiency and accuracy than a Lagrangian one. At least in
this presentation we will try to put into question this asseveration.
For this purpose we will present a pressure--‐segregation method with an
explicit time integrator for the momentum equations without the CFL
