Ocean Modeling Discussion

Hi all, I have some questions regarding ROMS: 1. I can make vector velocity of u-eastward and v_northward because they have same position. Do you have any idea how to plot vector velocity for u and w? Because they have different position, u (x_u,y_u,s_rho,ocean_time) and w (x_rho,y_rho,s_w,ocean_tim...

Well noted. Thanks John for your information.
I will check again my input file.

Hi all, Is there anyone here who has experienced an error when run restart file in cygwin ROMS? previously I managed to run restart file on linux by replacing NRREC = -1 and ininame = roms_rst.nc. When I run it in cygwin because I moved my device with Windows OS, my model experienced a blow up after...

Hi John, Thanks for your suggestion, my model is able to run without blow up again. I also want to ask you regarding the surface erosion rate. I read your paper "Development of a three-dimensional, regional, coupled wave,current, and sediment-transport model" and from equation 23 in your p...

Hi all, I don't know if my problem is faced by the others. I already used roms during this 6months and get the .nc file as a result. Until 2 days ago, I updated Ubuntu to 20.04. and when I try to run ./build_roms.sh, I get a notification: "mod_netcdf.f90:19:10: 19 | USE netcdf 1 Fatal error: Ca...

Hi Steven, Thanks for your information. I really appreciate it. Anw, when I modified the estuary test case (domain is same, change into flat seabed, without river flow, constant flow from western edge) and tried to change the lateral boundary condition in sediment input file, I found something inter...

Hi John, Thank you for your reply. I check roms_rst.nc file using ncview, what I got is a suspicious contour in the bottom right of bathymetry (bath.png picture). And when I checked in this location and plot the graph with xi_rho as the horizontal direction, bathymetry is suddenly dropped as shown i...

Hi John, Thanks before for your previous email regarding paper of shoreface-connected ridges in Fire Island. Actually, I want to investigate sandwave migration in detail. I made a rectangular domain with size 1200x300x30 m and sandwave seabed with 2m height and 300m wave length in ana_grid. My dx=dy...

Thanks all, I think i have solved the problem successfully by using a python code. I create my d3d grid and make bathymetry in delftdashboard and generate _roms.nc. Then I use my python code to generate the ROMS readable _roms.nc and convert it to swan.grd using COAWST matlab script. Let me know if...

Hi all, I am a new user using easygrid. Before I just used ana_grid.h in ROMS to try test case. Right now, I want to create my own grid, it's similar with estuary test case in ROMS but this rectangular domain has sinusoidal seabed. And I want to use width and length of domain data only without lat a...

Thank you very much John.
Your feedback is very helpful.
I will check article that you recommend.

Hi everyone, My question is not related to blowing problem, but for modelling sandwave in ROMS. I used estuary test case as a domain with flat seabed and tidal forcing condition. I try to check whether I can activate ripple geometry or not. I hope if ripple can generate in this test case, I can mode...

Hi all, I am already able to compile ROMS estuary case and right now try to plot using Matlab. But I found the difference between my result and wikiroms result (https://www.myroms.org/wiki/ESTUARY_TEST_CASE). I try to compare my plotting result with a figure in this website. 1. For example in MY25 d...

Hi Scarlet and Mnemoniko,

Can you solve the problem? Any solution about that? because I also have a same problem. Need your advice. Thanks before
