Ocean Modeling Discussion

I have tried with Fsclamped and m2reduced both at the eastern and western boundaries. At the beginning, elevation grows. the velocity computed by m2_reduced is positive at west, negative at east. Almost symmetric. (water enters from both sides....) As always, the blowup occurs when tidal elevation i...

Thanks john and thanks nobu! I have not solved the problem yet... :( The longshore tidal current U(t) must be prescribed and can not be derived by the surface gradient. Therefore I cannot use M2reduced. Further, I do not have a main current direction.. since the current is sinusoidal... so no main l...

I have a bowup problem. I probably need some basic help in the chioce of boundary conditions. I have a fairly regular bathymetry 300 m x 2040 m, with DX=5 m and DY=10 m with the coast at SOUTH (beach in Y=0, the rear land reaching level + 5 m in Y=-40 m) the open sea at NORTH (Y=2000m, depth of 10 m...

Thanks! Indeed I solved the problem by modifying snc_roms_getgrid.m a) line 33; <I> b) line 140; h=x_rho*0; h(1,1)=20; h(2,2)=-20; %these command are placed before before hmin=min(min(h)); %20 and -20 are the upper and lower limits of our bathymetry c) line 172; <comment>; <replece>; It is possible ...

Thanks Kate for your advices (here and in my question about wave_time)!! Well, in my application (for my graduate thesis on december) I want to study sediment trasport in a bathymetry with a trench dredged perpendicular to the shoreline. Because I'm a very beginner in modelling and so in Roms, I sta...

Hi, I want to plot my Roms output with matlab tool Rslice. In Rslice the default start variable is bathymetry h; but in my Roms application my bathymetry can change with time and so it is a 3D variable calls 'bath'. If I want to use as the startup variable 'bath' rather than h, I type: f = /home/mic...

Hi, I have a question about what is default Roms internal unit for wave_time and how can I apply a scale factor to my forcing netcdf wave_time unit. My forcing netcdf wave_time unit is in hours; I can scan (with ncview) each netcdf variable (Hwave,Lwave,Dwave..) along wave_time dimension for 193 tim...

Hi to all! i have run various test cases today with ROMS 3.0: 1) COUPLING_TEST, TEST_HEAD and maybe A4DVAR_TOY, and INLET_TEST require SWAN_COUPLING ?= on in the makefile.But this isn't my problem:they require Mct and I don't have it at all! Do i install it?And can i install now? I didnt know nothin...

thanks Sachin! It works. I tested many applications.But in some of them the following error messages appeared: 1)in test_head: In file ocean_coupler.f90:18 USE m_MCTWorld, ONLY : MCTWorld_init => init 1 Fatal Error: Can't open module file 'm_mctworld.mod' at (1) for reading: Nessun file o directory ...

Ok Sachin and thanks for reply!

To run other test, i type:

make ROMS_APPLICATION=BENCHMARK
make: Nothing to be done for `all'

so i type :

export ROMS_APPLICATION=BENCHMARK
export FORT=g95
make
make: Nothing to be done for `all'

...an error?

Hi to all! I 'm novice! i'm trying to compile Roms on my linux with g95 compiler,I would confirm if i did it well!After Netcfd's installation (in /usr/local/lib and /usr/local/include), after changing FORT=g95 in Makefile, I go in roms/trunk directory and type : export NETCDF_LIBDIR=/usr/local/lib e...

Thanks! You are right!Smartsvn looks better! I proceed ,to update roms,as follow : the root path is /home/michele/Desktop/roms/trunk , so i click on the icon 'update local working copy from repository' and i chose Update to HEAD. A window appears where: in repository : https://www.myroms.org/svn/src...

Hi to all,i'm very novice user and i need help! I install esvn. When i launch esvn from command line an 'error' appears as follow: michele@dream:~$ esvn X Error: BadDevice, invalid or uninitialized input device 169 Major opcode: 145 Minor opcode: 3 Resource id: 0x0 Failed to open device X Error: Bad...
