homogeneous temperature

[marilia_ag@yahoo.com.br]

The heat seems to be transmitted very fast in a MOHID experiment carried out. I got the following:

I did an experiment with 5 layers in a lagoon
with about 50 m depth. I put the following initial distribution of temperature
20 20, 25, 30 and 30 degrees from the bottom to the top.

The results show an initial condition the temperature field in agreement with my initial condition, but in the second time step the temperature
becomes almost 25 degrees in all levels, and in the third time-step it becomes nearly homogeneous.

I think it is to fast to have an homogeneous temperature (my time step is only 30 s). Someone has som experience with this results?

Thanks

Hi Marilia,

It is difficult to say what is happening and you'll need to be more specific.

1) What is the vertical turbulence model you're using?
2) What is the light extinction parameterization you're using?
3) What is the salinity distribution?

Best regards,
Luis
