! Shallow-water model with Euler advection. ! The variables below must be set in order to correctly configure ! the shallow-water model. ! Other variables (if present) can be left as-is. For namelist: NAMDYN TSTEP=300.0, ! reduce timestep for Euler stepping REPS1=0.01, ! turn on Asselin time-filtering coefficient REPS2=0.01, LHDIFFM=.false., ! horizontal diffusion on / off LSETTLS=.false., ! extrapolations in SL scheme LSETTLST=.false., ! ditto For namelist: NAMCT0 NCONF=201, ! model configuration: 201 = shallow-water (see yomct0.F90) LSLAG=.false., ! turn off semi-lagrangian scheme LTWOTL=.false., ! disable two-time-level SL scheme. LRFRIC=.false., ! turn off Rayleigh friction LSLPHY=.false., ! turn off split time-step physics LVERTFE=.false., ! turn off vertical finite element scheme N2DINI=1, ! initialise 1 = Haurwitz wave, 2 = real fields LSPRT=.false., ! if T temperature is 'virtual temperature' LFPOS=false, ! turn off fullpos diagnostics, does not work with SW N3DINI=0, ! no 3D initialisation NSTOP=600, ! no. of steps to run NFRHIS=10, ! frequency of results output For namelist: NAEPHY LEPHYS=false, ! turn off ECMWF Physics package (master switch) LERADI=false, ! turn off radiation scheme For namelist: NAMDYNA LGRADSP=.false., ! disable de-aliasing the pressure gradient term For namelist: NAMDIM NUNDEFLD=0, ! make sure uninitialised variables are all set to zero |
Also, add a blank namelist to fort.4 for NAMSWE:
