Hi,

 Why I  get the following message, while the water level is below the lake outline?

It looks like something may have gone wrong in the code. As a NaN values has been generated.

Can you send me your setup files and I will have a look.

Hi Mahyar,

Your DINOF variables has gone unstable and has extremely large values.  Trying to simulate 6 algal groups is a big job are you sure need to simulate all of these?

Hi Chris,
I run the same model with CAEDYM version 3 and the model works for whole summer. Is there any big difference between AEM3D and CAEDYM version 3 which causes the instability?
I also hear that CAEDYM version 3 in not good at simulation of dissolved oxygen. If this is true has this problem been solved in AEM3D?

My guess is your DINOF were still blooming unrealistically in CAEDYM.  The new water quality model does a much better job of maintaining conservation of all variables so these unrealistic blooms hopefully will not occur.
