Basic Hydrostatics & Stability
This issue has to do with the initial waterplane height for the free-float iteration. When you specify a weight (and/or cg) for the hydrostatics, the soluti...

Although Orca3D uses a mesh to compute most of the hydrostatics, certain quantities can only be computed from stations. These include the prismatic and maxi...

This usually results from Orca3D not being able to find an equilibrium. Often the cause is a surface edge becoming submerged, such as the deck edge when the...

Possible reasons for this include:
If you have modeled only half of the hull, but not checked the “Mirror About the Centerplane” box, your valu...

Surfaces in Rhino have the concept of an “inside” and an “outside.” The outside should be the side in contact with the water; if not, the volume of that sur...

If you have two surfaces joined in a station plane that coincides exactly with one of the station locations that you have defined, Orca3D will com...

Incorrect results are possible when the waterplane
intersects interior "dry" surfaces, either in an upright or heeled
condition. ...

The Orca3D Hydrostatics & Stability module can be used to simulate a flotation experiment, where a hull is placed in the water and then weights are adde...

Performing a hydrostatics analysis on a multihull in Orca3D should be no different than doing it on a monohull. Make sure your hull(s) is/are placed in the ...

If you see this error, it usually means that there is a surface that Rhino is having trouble meshing. You can first try selbadobjects and if Rhin...
