module pbpush2d
!
! Fortran90 interface to 2d parallel PIC Fortran77 library pbpush2lib.f
! pbpush2mod.f contains interface procedures to process particles with
! magnetic fields:
! defines module pbpush2d
! djpost => ipgjpost2 deposits current density, with various
! interpolations and optimizations.
! calls PGJPOST2, PGSJPOST2, PGSJOST2X, PGJPOST2L, PGSJPOST2L,
! PGSJOST2XL, PGJPOST22, PGSJPOST22, PGSJOST22X, PGJPOST22L,
! PGSJPOST22L, or PGSJOST22XL
! push => ipgbpush2 push particles with magnetic field and 2 component
! electric field, with various interpolations and optimizations.
! calls PGBPUSH2, PGSBPUSH2, PGBPUSH22L, or PGSBPUSH2L
! push3 => ipgbpush23 push particles with magnetic field and 3 component
! electric field, with various interpolations and optimizations
! calls PGBPUSH23, PGSBPUSH23, PGBPUSH23L, PGSBPUSH23L,
! PGBPUSH22, PGSBPUSH22, GBPUSH22L, or PGSBPUSH22L
! retard => ipretard2 retard particle position a half time-step.
! calls PRETARD2
