test - experiment : adjustment.cs_32x32x1 (.nlfs)
purpose:
test the non-linear free-surface in a simple barotropic adjustment
problem.
this experiment was identical to standard "adjustment.cs_32x32x1" (before
this later got changed to an oceanic test on Apr 18, 2009) except:
* use NonLin-FreeSurf
(CPP_OPTION.h : "#define NONLIN_FRSURF" and nonlinFreeSurf=3 in data)
* use a Cranck-Nickelson time stepping (implicSurfPress=implicDiv2DFlow=1/2)
to compute the free-surface pressure anomaly.
* use a smaller time step for a better resolution of gravity waves and
a larger initial surface pressure anomaly (100.mb) to increase the
non-linear effects.
