Not here, but it other functions it would be very useful to be able to map back to the owning particle. In fact, I have to treat local and ghost particles differently. In terms of updating properties, I only need to update the properties of local particles. When the maximum displacement of a particles reaches half of the cell length in the triangulation, I call sort_particles_into_subdomains_and_cells() to update the list of local and ghost particles. I can explain the algorithm in more details if you want. Thanks again. Shahab
