Have you opened the tool to add stations, buttocks, waterlines, and diagonals?
Also, make sure your model’s extents exist within the range in which you are adding those stations, buttocks, and diagonals, and waterlines. Is it possible you have mirrored, moved, or otherwise transformed the model outside those limites, or to something the hydros will not calculate for?
Interesting model, though. Let us know what presumed speed it can attain surfaced and submerged, as far as Delftship reports. What resistance calcs you come up with would interest me, too.
May to calculate the resistance in 10m merged, in other depth get is interest dates.
Max speed 25 knots, test depth is 800 feet. The submarine name is USS Virginia. Length 377 feet (115m), beam 34 feet (10m), 7900 metric tons. The model is not all (the displacements is too large) yet.
