Error MAIN: Abnormal termination: BLOWUP

[BrunnaSimonetti]

Hi everyone, I'm new user of ROMS, and I am having problem when running my model.
I would like your help follows the error message, and the header file.

That you have NaN for the energy and volume before the run even starts suggests that you input initial conditions contained NaN.

View the standard output where it reads initial conditions. You'll see something like:

NLM: GET_STATE - Read state initial conditions, t = 00 00:00:00
(Grid 01, File: yourfilename.nc, Rec=0001, Index=1)
- free-surface
(Min = -4.28777677E-01 Max = 7.12206929E-01)
- vertically integrated u-momentum component
(Min = -5.69404529E-01 Max = 6.04521196E-01)

The Min/Max values should be physically reasonable values.
