module mppush2d
!
! Fortran90 interface to parallel 2d PIC Fortran77 library mppush2lib.f
! mppush2mod.f contains multi-tasking interface procedures to process
! particles:
! defines module mppush2d
! dpost => impgpost2 deposits charge density, with various
! interpolations and optimizations.
! calls MPGPOST2, MPGSPOST2, MPGSOST2X, MPGPOST2L, MPGSPOST2L,
! or MPGSOST2XL
! push => impgpush2 push particles, with various interpolations and
! optimizations.
! calls MPGPUSH2, MPGSPUSH2, MPGPUSH2L, or MPGSPUSH2L
! pushzf => imppush2zf, push particles with no forces.
! calls MPPUSH2ZF
! sortp => impsortp2y sorts particles by y grid using memory-conserving
! bin sort, with various interpolations.
! calls MPSORTP2Y, or MPSORTP2YL
! sortp => imdpsortp2y sorts particles by y grid using optimized bin
! sort with various interpolations.
! calls MPDSORTP2Y, or MPDSORTP2YL
! gcjpost => impgcjpost2 deposits time-centered current density with
! 2d electrostatic fields.
! calls MPGCJPOST2, or MPGCJPOST2L
