Re: locally increasing grid resolution using seagrid
You can certainly increase the resolution with seagrid, but since it is a structured grid you´ll have a strip of high resolution all along your grid from east to west and from north to south. Then you´ll have an area (for example in your eastern border) with high resolution and deep bathymetry, whic...

Re: Why I got such a different tide solution using TPXO data
Hi stone,
I see you´re using ANA_FSOBC and Chapman boundary conditions. Maybe there´s a conflict there. Have you checked this?

Re: Problem using ana_m2obc
Hi Kate. Thanks for the reply. I´m running serial, so I guess it´s complaining about ana_m2obc.h. I used ana_m2obc I downloaded along with ROMS code and just modified after the "else" part: #else ... # ifdef WEST_M2OBC IF (WESTERN_EDGE) THEN DO j=JstrR,JendR BOUNDARY(ng)%ubar_west(j)=-0.65...

Problem using ana_m2obc
Dear Rommers, I´m trying to model a large and flat river in the Amazon basin. I have information of flow and velocity in the western boundary, wich I fit to an analytical expression and I´m trying to use ana_m2obc to force the model. When compiling the model I receive this error messages: analytical...

Re: Confused about test cases
Hi bibi951, I didn´t go through the equations yet to check why it blew up at the boundary (and to be honest I´m not quite sure if I´ll do it...). What I can tell is that the problem is on the barotropic velocity at the boundary. The combination of reduced physics with M2FLATHER makes it unstable. My...

Re: Confused about test cases
Hi bibi951 and all, Just for the record, about my previous post. I found the problem I was facing about small tidal amplitude (and of course, was my mistake! :oops: ). So in order to help others that might face the same mistake... The problem wasn´t on the tidal velocity ellipses estimation for forc...

Re: Confused about test cases
Hi bibi951, I was facing the same problem, i.e. small tide amplitudes compared to observed and even to the forcing imposed. Then I checked the following discussion https://www.myroms.org/forum/viewtopic.php?f=14&t=854 and used the FSOBC_REDUCED cpp option. The tidal amplitudes are now much close...

Re: Strange wind stress behavior
Yes. There are some backward steps on the sms_time variable. I´ll correct that.
Thank you!

Re: Strange wind stress behavior
I think you got the point. The output (see below) shows that last stress reading was on day 273 - 06:00. At 12:00 it should have read the next field, but it didn´t until the end of the run. The ECCO fields are being normally read though. Do you know why this is happening? Thank you. Mauricio Fragoso...

Strange wind stress behavior
Dear all, I´m running ROMS 3.0 for southwestern Atlantic Ocean using ECCO data (every 10 days) for initial and boundary conditions and NCEP winds (every 6 hours) for atmospheric forcing for a 2007 hindcast. I had to interrupt the run two times and performed a restart at day 140 and day 200. I found ...
