Thanks Mr. Wilkin! I had intentionally changed all my LBCs to Closed from Chapman and Flather because I had removed ANA_FSOBC and ANA_M2OBC from my header file and keeping the Cha and Fla would prompt ROMS to ask for rooms bry.nc file, which I am not using. Anyways, working again on your suggestion ...

neelbasak08

Thanks Mr. Wilkin! As per your suggestion, I remove ANA_SMFLUX from my header file and removed ANA_FSOBC and ANA_M2OBC as well. Just defined bulkflux and other previous headers. I see an improvement in my velocity profile where its order changed from a factor of 10^(-4) to 10^(-3), but it's still ...

Well, Thanks, Mr Wilkin! As in my log file, I can see that wind data has been read from my input forcing file itself.

Hello! I am for the first time trying to do something of this kind in ROMS 3.9.

You can't have a tidal boundary condition file for the nested grid. It gets its boundary conditions from the parent. Thanks Mr Wilkin! As you said that the nested grid should take its tidal forcing from the parent grid, I tried that now by removing the child grid's forcing file in both TIDENAME and ...

Thanks Mr. Wilkin ! Now, I am facing a different issue altogether.

Hi Lawrance, I think in the last release of GridBuilder I made it so that bathymetry modifications only affect unmasked parts of the grid, so that setting a minimum depth would set that value where the unmasked depth was less the minimum. Bathymetry that was masked remains as it was and for land ...

Hello Subrat, I might suggest you visit post number 79 in this same thread. It has the lines that were missing in an earlier version of TPXO2ROMS. When I added those lines, it showed no error and generated my files successfully. Actually, the earlier version as far as I can recall didn't use the ...

neelbasak08

Dear Subrat, I apologize, Mr. Luick, the double dot was indeed a typo. I believe you slightly misunderstood what Mr. John Luick was trying to say by the line " Let us say you want your model to start at 0000 hours on 14 April 2021. Then TIDE_START=datenum(2021,4,14)-datenum(19678,5,23). The second ...

neelbasak08

Dear Subrat, I am a bit confused about the part where you said " If possible kindly make my confusion clear about the use of data file." I am not sure about the term data file or anything special other than the grid which may be used for ROMS. As for the atlas version, I used it 2 months back and it ...

neelbasak08

Hi John Luick, It will be great, if you could suggest, what steps and/or scripts should I follow and/or use to generate tidal forcing data-sets using TPXO9-atlas-v4 netcdf bearing the following tidal components = "M2, S2, N2, K2, K1, O1, P1, Q1, Mf, Mm " for my ROMS Grid. Thanks, Subrat Centre for ...

neelbasak08

Thanks, Mr. Wilkin! Another thing which I wanted to ask is that, is there a way or MATLAB script in ROMS that can show the value of given variables at certain a given depth in tabular format? What I mean is that for example, I need to get a tabular form of u momentum component velocity at a certain ...

neelbasak08

Thanks a lot, Mr. Wilkin! I updated the code from GitHub and it works just fine. Again another thing I wanted to confirm is that the documentation of these routines is the same as the one in TiddlyWiki right? Again thanks for providing the plot package. It's super easy to use and user friendly Kind ...

neelbasak08

Thanks Mr. Wilkin for your reply ! Earlier I'd been using the version I had downloaded via svn though I hadn't changes anything in that and ran it command line just. And I am sorry I didn't read the part in one of your previous posts mentioning that now you maintain it in your git repository. I was ...

neelbasak08

Thanks Mr. Wilkin, Yes, I did test some other variables like ubar in roms_zview but I believe it's a 2D parameter therefore having depth was no sense there and MATLAB plotted the results anyways. Yes, the roms_sview worked fine with date input as a string. I followed your debugging suggestion. It ...

I was successful with plotting the upwelling results with your package. But as I try to implement them on my output files of ...

neelbasak08

Thanks Kate ! Can it be an issue with the mesh that I'm using ? Maybe ROMS isn't able to read every parameter from the grid file I'm using ? I'm not sure about that as I just changed my resolution in my previous and it happened to stop. Can it be an issue with my bathymetry or forcing files ? I ...

Thank you Mr Charles ! I had another query. This one is regarding masking during grid generation in GridBuilder.

I usually make grid of L300 x M150 but in order to make my run faster I changed it to L100 x M50 but it seems the simulation speed has increased but not so significantly. I shall double the DT parameter and see how that works for me. I had ...

neelbasak08

1. What size grids did you use in these different tests? (xi, eta, and vertical dimensions) 2. Have you tried using OpenMP? 3. What are your CPP options? Thanks Kosa , my usual go to grid size is L300xM150; Well xi and eta differs from case to case. When making grids for a large region my xi x eta ...

Hello ! I was wondering in what ways one can speed up model run in ROMS while using serial computing ? Does having a coarse mesh affect runtime ? Because when I try to reduce my runtime by just making the mesh coarser and coarser, it doesn't show any significant change in the runtime. Am I missing ...

neelbasak08

Thanks Kate ! I don't think so I changed anything in ana_initial . Because I am able to run a different model based on exact same configurations in ROMS using same parameters and just changing the grid, wind and tidal forcing files. But when I run this model, it ends up abruptly. I was wondering ...

Hello! I have been using ROMS for the past 1 month and now I require to use nested grids for my ROMS model purposes. I had previously created my own grid which was coarse in nature. Then I tried to use matlab routines provided with ROMS package such as coarse2fine.m and contact.m for this purpose ...

neelbasak08

Offline nesting is running two completely independent domains, except one is nested within the other. You run the larger domain first, saving daily or whatever. Then you run a script to extract boundary conditions from that domain for your smaller domain. Then you run that by itself. The child grid ...

neelbasak08

You are talking about doing online nesting in that case. I have a lot less experience with that than with offline nesting. I am not sure what's the difference between online and offline nesting. I'm using MATLAB script to create my finer grids and trying to follow the instruction as demonstrated in ...

neelbasak08

When doing offline nesting, each domain is a fully independent domain. You run the larger, coarser one first, then use fields from that domain to create the initial/boundary files for the smaller domain. This creation of boundary files for the child grid happens offline, for instance with pyroms ...

neelbasak08

Is this online or offline nesting? If online, the nest needs to be a very specific subgrid of the parent, at an odd ratio such a 1:3, 1:5, etc. If offline, just make another grid as you normally would. It can be at any orientation as long as it is entirely within the parent domain. If online, I ...
