SPINS Cases

SPINS comes with a variety of case files which (should) run without any problems. Below is a list of currently available cases with a description of their purpose.

derivatives

Computes secondary variables (vorticity, enstrophy, dissipation) and derivatives of flow variables (velocity, density, temperature, etc). See SPINS derivatives for more information

NOTE: If the v-velocity exists (flow is 3 dimensional, or periodic in the span-wise direction of a 2 dimensional case) then the option v_exist=true must be set.

dipole

Crashing of a dipole into a wall. See the theses by C. Subich and K. Rowe and the reference therein.

gravity_current

The simplest of cases. Creation of a bottom gravity current originating from the collapse of a region of high density fluid.

kh_billow

Formation of Kelvin-Helmholtz billows by shear in a stratified pseudo-two layer fluid.

map_iwave

Formation of internal waves from tidal forcing of a stratified fluid over a ridge. See the thesis by C. Subich.

mode1_mode2

Formation of a mode-1 and/or mode-2 ISW in a closed tank. Each wave can be turned on or off. Made to be as close to laboratory experiments as possible.

mode2_ISW

Like mode1_mode2 but with only the mode-2 ISW. Double pycnocline is also an option. See Deepwell et al. (2016) and Deepwell et al. (2017).

wave_reader

Starting simulations from data originating elsewhere. This data might be created in Matlab (see Matlab-to-SPINS grid ordering) or to be extending a 2D simulation to 3D.

nleos (Under construction)

Choosing a different equation of state. Choices include a simple linear 2 constituent (heat/salt) equation of state, simple quadratic equation of state (for freshwater near the temperature of maximum density), and a full nonlinear equation of state.
