Detailed Description

This module contains the methods used to allow storage parameters in the STO package (specific storage and specific yield) to be varied throughout a simulation.

tvs_reset_change_flags()

subroutine tvsmodule::tvs_reset_change_flags ( class(tvstype)  this )

private

Deferred procedure implementation called by the TvBaseType code when a new time step commences, indicating that any previously set per-node property value change flags should be reset.

    ! -- dummy
    class(TvsType) :: this

subroutine tvsmodule::tvs_set_changed_at ( class(tvstype)  this, integer(i4b), intent(in)  kper, integer(i4b), intent(in)  kstp  )

private

Deferred procedure implementation called by the TvBaseType code when a property value change occurs at (kper, kstp).
