Attached an example of top interface anomaly at velocity points (on expect something like the sea level anomaly) defined as the vertical sum of scale factors minus total depth at rest. = Analysis = Gurvan's aware. = Fix = One should at least ensure that top interface matches sea-level anomaly at u and v points. Correct definition ot the bottom most interface is more tricky across steps.",Defect,closed,normal,,DOM,trunk,minor,fixed,VVL scale vertical,greffray
