STIM provides a common interface of ice models to hydrodynamic models.
The aim is to separate the actual ice algoorithms from the hydrodynamic model such that only a well-defined small interface is needed in order to test and use a variaty of different ice models.
As a proof of concept two different models are included in this initial release. Also included is a driver for GOTM.
Source code documentation
The API for do_stim in the GOTM-driver has changed between the legacy and master branch:
Legacy
subroutine do_stim(dz,dt,Tw,S,Ta,precip,Qsw,Qfluxes)
Master
SUBROUTINE do_stim(dz,dt,ustar,Tw,S,Ta,precip,Qsw,Qfluxes)
!! Arguments
real(rk), intent(inout) :: dz
!! layer thickness [m]
real(rk), intent(inout) :: dt
!! time step [s]

!! surface friction velocity [m/s]
real(rk), intent(inout) :: Tw
!! water temperature [C]
real(rk), intent(inout) :: Ta
!! air temperature [C]
