Blow up ROMS model.

#1 Post by kobl1201 » Tue Dec 20, 2016 12:58 am

Dear All.,

My model is blowing and I don't know why. I tried to change DT(10sec -> 5 sec) but I saw same things.

I put boundary condition every day, and atmospheric forcing applied every 6 hour.

I check Input data, but it is fine.

I think if the input data is wrong, the model would blow up first step. However, the model calculataed first step, and then blowed up.

138242 56996 00:00:10 NaN NaN NaN NaN
(134,246,41) 4.399374E-05 Inf 2.628991E-06 1.429563E+00

Please Help me~

Thank you

Kates's FAQ would be helpful to you.

For me, I would save every snapshot as possible as I can(here give NHIS==1), and then I plot every field

along all levels. You will find something.
