Hi, here is the simulation file

Hi

I'm sorry I didn't notice the compressed file size. The UVH binary file of TPXO is too big.

Please ignore the posts that I did not attach successfully, I will attach my simulation file again. Very sorry for duplicate replies.

Hi Yang,

First of all, I think you should go step by step and add complexity progressively to your case.
Did you run a 2D model first with only tide? then a 3D with only tide? after that, you can try adding the regional circulation.

You didn't provide the execution log of your model, but according to what I see in your steering, there are a lot of things that explain your model can't correctly run, even in 2D with only tide:
- your mesh is in lat/lon real degrees, and you set GEOGRAPHIC SYSTEM = 5 which is not correct, no need to provide ZONE NUMBER IN GEOGRAPHIC SYSTEM in this case.
- COEFFICIENT TO CALIBRATE TIDAL VELOCITIES = 250 ! is it really what you want?
- Nikuradse coefficient for bottom friction law = 5m, is it really what you want?
- PRESCRIBED ELEVATIONS and VELOCITIES : 2 values provided, only one boundary..
- use_fortran: you didn't provide your modifications..
- 5 vertical levels, it's not much..
- TRACERS VERTICAL PROFILES = 0 -> you didn't provide your implementation

In a general way, your steering file is really a mess. Try to regroup the processes and related options to make it clearer.

So please, come back to simple case of tidal 2D simulation (maybe with a larger domain, yours is really small for tidal and regional circulation).
After this stage, you can try to extend it in 3D.

I hope it helps,

Hi, Laurent

Actually I started the simulation from a simple tide, under the guidance and study of the forum, 2d and 3d simulations were successful in the case of TPXO and wind 2 previously. I currently want to use the HYcom global model to enhance UV and add temperature and salinity. The only problem is that the mesh is the new one.

I'm sorry for some of these inadequate parameter settings, and mess steering files. I just want the UV in the result file changes at a higher level. Like you said, the UV of currents value in my area has less influence.

OK, I will increase the complexity of the steering file step by step on the new mesh. Thank you very much for pointing out my problem. its helps me a lot.

Best regards
Yang
