  In this paper, a new progressive mesh algorithm is introduced in order to
perform fast physical simulations by the use of a lattice Boltzmann method
(LBM) on a single-node multi-GPU architecture. This algorithm is able to mesh
automatically the simulation domain according to the propagation of fluids.
This method can also be useful in order to perform various types of simulations
on complex geometries. The use of this algorithm combined with the massive
parallelism of GPUs allows to obtain very good performance in comparison with
the static mesh method used in literature. Several simulations are shown in
order to evaluate the algorithm.
