the problem is that the 3D vars in that file are > 2 Gbytes, eg

   float v(ocean_time=351, s_rho=36, eta_v=253, xi_v=224);

So you need to use the large format, and i think theres currently not a way to
specify that on on that interface. Ill have to add that.

but are you sure you want to write a file that big?
