| amrex::DenseBins< WarpXParticleContainer::ParticleType > | ParticleUtils::findParticlesInEachCell (int const lev, amrex::MFIter const &mfi, WarpXParticleContainer::ParticleTileType const &ptile) |
| | Find the particles and count the particles that are in each cell. More specifically this function returns an amrex::DenseBins object containing an offset array and a permutation array which can be used to loop over all the cells in a tile and apply an algorithm to particles of a given species present in each cell. Note that this does not rearrange particle arrays. More...
