We propose an implicit way to solve the fluid dynamics equations discretized following the Smoothed Particles Hydrodynamics approach. We applied it only to ideal gas dynamics problems. The proposed algorithm is very stable and a gain of a factor 10 can easily achieved for any kind of problems. We foresee that the computational gain will be larger for cases heavily constrained by Courant condition, like the ones occurring in magnetohydrodynamics. © 2000 American Institute of Physics.
