Intro

This is a basic but common test to verify the integrity of the model equations. This test is also good to show different type of boundaries reflect waves.

Goal

Check that the solution produces symmetrical results
Test hotstart condition
Show how different boundary formulation absorb wave

Settings

You will need:

Flat bottom bathymetry file. (See below)
Hotstart file. here only water level is needed to hotstart the water surface (zs)

Bathy

Initial conditon

Here we follow a similar initial condition as in Basilisk

BG_param.txt

bathy = bathy.nc?z;

Model controls

gpudevice = 0; spherical = 0; theta=1.3; doubleprecision=1 zsinit=0.0 hotstartfile=zsinit.nc

Flow parameters

eps = 0.00010000; cf=0.0000; frictionmodel = 0

Timekeeping parameters

CFL = 0.500000; outputtimestep = 600.0; outvars = zb, hh, uu, vv, hhmax, zs, zsmax; endtime = 18000.0; left=2; right=2; top=2; bot=2; topbndfile=bnbzero.txt; botbndfile=bnbzero.txt; rightbndfile=bnbzero.txt; leftbndfile=bnbzero.txt; smallnc=0; outfile = Testbed-Gaussian.nc;
