Type-Bound Procedures

procedure, public :: init

  • private subroutine init(self, comm)

    Initialise snapshot manager

    Arguments

    Type IntentOptional Attributes Name
    class(snapshot_manager_t), intent(inout) :: self
    integer, intent(in) :: comm

procedure, public :: handle_restart

  • private subroutine handle_restart(self, restart_iter, dt, comm)

    Prepare to continue the snapshot file of the run being restarted. Steps up to the restart time are kept and later ones (written past the checkpoint) are dropped, so the restarted run appends without duplicating them, whatever snapshot frequency wrote the file. The file's layout is kept so the first snapshot can check it still matches the output settings.

    Arguments

    Type IntentOptional Attributes Name
    class(snapshot_manager_t), intent(inout) :: self
    integer, intent(in) :: restart_iter
    real(kind=dp), intent(in) :: dt
    integer, intent(in) :: comm

procedure, public :: handle_snapshot_step

  • private subroutine handle_snapshot_step(self, solver, timestep, comm)

    Handle snapshot writing at a given timestep

    Arguments

    Type IntentOptional Attributes Name
    class(snapshot_manager_t), intent(inout) :: self
    class(solver_t), intent(in) :: solver
    integer, intent(in) :: timestep

procedure, public :: finalise

  • private subroutine finalise(self)

    Clean up snapshot manager

    Arguments
