NaN in grainmass during dustgrowth simulations

[AlagueroA]

As the title says, some SPH particles have a grainmass equals to NaN during dustgrowth simulations.

The particles that have a NaN grainmass also have a huge Stokes number (St) and so a huge stopping time (ts).
NaN values seem to appear when the particle fragment close to the input minimal size.
