COHERENS forum

Hi Sou, What exactly do you mean with periodic? What kind of boundary condition did you have in mind? Because inducing a periodic condition is not that difficult if you include time and/or a wave function in the program setup? HI, Could you please tell me how include time and/or a wave function in ...

I don't have this option (IOPTM) in coherens2. IOPTM Determines the type of meteorological forcing. 0 : Surface stress, heat fluxes, salinity fluxes and solar radiation are zero. 1 : Surface stress is constant in space and time. Heat fluxes, salinity fluxes and solar radiation are zero. 2 : Surface ...

Dear Katrijn, It showsthat the size for both is 1. I set iopt_grid_htype = 4 but, now it shows this error in errlogA Invalid value for integer parameter iopt_grid_htype: 4 Must be between: 1 and 3 A total of 1 errors occurred in check_mod_filepars Error type 7 : Invalid initial values for model para...

Hi, anyone knows why this error shows up with this piece of code? The error shows up at last line of the run. I found the problem is with : surdata(i,j,1) = uwindatu_cst; surdata(i,j,2) = vwindatv_cst when I use i,j , otherwise the program runs normally. My Code: !===================================...

Hi,
I'm trying to plot UVEL in a rotated coordinate , how should I plot it? where should I set new x, y?
Thanks,

Hi Kat, I'm defining a wind farm in a Lake, at the moment I'm considering a 20km by 20km rectangular open water with a uniform depth of 25m. now I want to divide my rectangle into for example 16 squares of 5*5km. I want to put a turbine in the middle of each square and I want to apply periodic bound...

Hi,
Is that possible to set a periodic boundary condition in the model?
Sue

Thank You Kat, the problem was caused by jj=0 as you implied. now it lets me open all 4 boundaries.
Thanks again,
Sue

Hello, How can I define a rectangle open boundaries? it seems that the model doesn't let me consider all side as open boundaries. I tried to define a rectangle in water where all sides are open and the depth is uniform, here is the brief statement: !---grid dimensions nc = 11; nr = 11; nz = 25 !---n...

Hi, I'm trying to set a 3D usrdefine_model from the usr example file. but I think there is a problem. in part 4) Physical model constants of user defined model setup (example routines) file, in uniform surface exchange coefficient for latent heat: !---uniform surface exchange coefficient for latent ...
