Map a list of particles to a density. The order can be zero (map particle to the containing cell) or one (use bi/tri-linear interpolation). Note that ghost cells are automatically filled by this routine.
- Parameters
-
| [in] | iv | Variable to store density |
| [in] | n_particles | The number of particles |
| [in] | coords | The particle coordinates |
| [in] | weights | Weights for the particles |
| [in] | order | Order of interpolation |
| [in,out] | id_guess | Guess for box id containing particle, set to 0 where no guess is available |
| [in] | density | Divide by cell area/volume (default: true) |
| [in] | fill_gc | Fill ghost cells afterwards (default: true) |
