1/ Check if the carrier phase simulation is stable
>if not, choose a smaller mesh size or use a smagorinsky model until it becomes a stable set-up
2/ Check if the particle phase is stabel
> if not, choose a even smaller mesh size or choose a bigger diffusion coefficient until it becomes a stable set-up
