      Hello everyone.

      I’m new user of Delftship free software. I’m trying to get displacement and hydrostatic data from a model. When I try to calculate there si no any values for displacement and hydrostatic data. Also I have 19 leak points. I attached also the file.

      Thank you

      Hi Urse,

       

      Leak points will break functionality.

      I’ve had a (very) quick look at your model, and it seems that you have modeled both sides- in DELFTship it is common to only model the PS half of a vessel, the SB side is mirrored. When doing this do make sure al points at  heart ship have a y value of exactly 0.000. Otherwise make sure the layer you are using is set to be asymmetrical (in layer settings menu)

      Hi Maarten,

      Thank you for your reply

      I removed the all mirror surfaces. I create new surfaces without mirroring function. I still have 10 leak points.

      You can see in my model attached.

      Hi Urse,

      Yes, two points with the same coordinates are not the same point. This is the more tricky part of modeling in DELFTship. The most straightforward approach is to delete the leak points (one at a time!) and then add surfaces to repair the hole that this creates. Make sure that you try to keep faces as regular as you can (each face has preferably 4 edges, and 4 points).
