I am running the tides only model and keeping constant temp. But I have got the surface temperature as follow. I also found the temperature of all boundaries in the bottom layers are not constant. What's the reason for this?
Please find the attachment for my model's configure.

Re: how to keep constant temp when running tide only modal?
Though I have not defined TS_FIXED, I have set the initial conditions, OBC to T0(ng), and set the surface and bottom fluxes to 0, by ana_initial, ana_tobc.h, ana_stflux.h and ana_btflux.h.
So I really can not understand why the temperature can be changed still during the LOOP?

Re: how to keep constant temp when running tide only modal?
You don't need to define TS_FIXED for tide-only modeling. Just constant tempe/salt as you specified.
It looks to me that your problem may be something to do with open boundaries.
What's your cppdefs and ocean.in?
Also, why did you edit ana_tobc.h? I don't think I did that for tide-only modeling.

Re: how to keep constant temp when running tide only modal?
For a really simple tides-only problem you can turn off SOLVE3D. Then you won't have any temperature to be evolving. The one thing you would have to change in ocean.in is to set DT to your fast DT and NDTFAST to 1.

Re: how to keep constant temp when running tide only modal?
I just want to run 3D model, not 2D, though I know 2D is enough for tide only case.kate wrote:For a really simple tides-only problem you can turn off SOLVE3D. Then you won't have any temperature to be evolving. The one thing you would have to change in ocean.in is to set DT to your fast DT and NDTFAST to 1.
Thanks. Any other suggestions still?
