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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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
