MIGAL for Phoenics version 1.82 has
been introduced during the 9th Phoenics user conference. Since its first
release in 2000 MIGAL for Phoenics has been improved for robustness. In
particular, a new GMRES capability, new internal self-adjustments and new
default parameters have been introduced to facilitate and extend users'
control. To illustrate the new paradigm of this strongly coupled
multi-grid algebraic solver and the large benefits that one can gain in
using it, this paper firstly addresses the basics of the method. The
velocity-pressure coupling, the multi-grid procedure, the ILU smoother as
well as the momentum preconditioning technique and the GMRES accelerator
are investigated. A second part is dedicated to the solver preformance and
several laminar, turbulent, boyancy-driven and industrial flows are
discussed regarding the global non-linear convergence efficiency of each
case. For more information please download the

During the 8th Phoenics users conference in Luxembourg MFRDC and CHAM introduced MIGAL for Phoenics
version 1.62. For more information, in particular on the large speed-ups that
MIGAL produces or on the memory-cpu strategy, please
