Hi Saeid,

I don't know if there is anything special about the internal_wave output,
but I use the xarray and library to read nc data. It is used like this:

# import library
import xarray as xr

# open data set forn file 'filename'
dset = xr.open_dataset(filename)

# extract variable (V) and optionally, a subset of the variable
sub_selection = dset.V.isel(X=310, T=6, Y=slice(0,40))

The you can plot sub_selection using matplotlib.

There is a short tutorial here
<https://nbviewer.jupyter.org/github/bmooremaley/software-workouts/blob/master/tutorials/NetcdfAndXarray.ipynb>

Cheers,
Karina
