Re: Wetting and drying analytical test

Hi Pilar, For inter-model comparison of Thacker's bowl solution you might be interested on Lahaye et al. "A numerical scheme for modeling tidal wetting and drying". JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 116, C03028, doi:10.1029/2010JC006666, 2011. Note that it would be interesting to extend the solu...

Re: advection and spurious mixing

Dear all, I think that everything has been written. I just like to add one point (that maybe does not fit into this topic, feel free to move it). When I did the lock exchange problem on my personal computer (if you want details on its config contact me) with no other load than running ROMS, the UP3 ...

Re: Why I got such a different tide solution using TPXO data

Hi Stone, OK so as expected the tidal potential did not do much. Clearly your solution for semidiurnal and diurnal tidal phases and tidal amplitudes at the boundaries do not match TPX (especially at the Southern boundary) and it should. It is puzzling to me. So 2 things: (1) you're not prescribing c...

Re: Why I got such a different tide solution using TPXO data

Hi Stone, Although I do believe, like Kate, that in your case combining the remote tide coming from the open boundaries and the body forcing (local tidal potential representing the astronomical forcing in your domain) will not necessarily correct for all your differences (because of the low latitude...

Re: Simple method for calculating Numerically Induced Mixing

Hi Rich, I have just finished my PhD and my dissertation focus was about the numerical mixing. Specifically, I look at how different numerical choices (e.g., grid horizontal and vertical resolution, advection scheme) impact on the magnitude of the spurious mixing generated by internal wave propagati...

Re: Problems on run

I had this error message ** rank 0 in job 1 c0202_35389 caused collective abort of all ranks because I had computer memory issues. I increased the number of processors and it ran but I'm not sure this message is unique to this problem. But you could try... Could you also post the full log of your ex...

Re: Help My first application

I never tried that test case but if there is no land in your basin, try to undefine the MASKING option.
It seems that you have a NAN value for your min basin volume and a 0 value for your barotropic courant number. Start from there to debug.

Re: Running ROMS on the IBM p5-575 server

The problem is that ROMS cannot find your ocean_upwelling.in (usually located in the External directory). So either you don't have it or you have a mistake on specifying your paths.
