HI Petter,
thanks for that tip. I am just rerunning the model to get some output
closer to the point of the crash, because I don't have any data round
there and so can't tell right now what went wrong. If it turns out to be
surface sea level I would most certainly like to know how I could fix
it. I'll let you know.
