Analyze Mass Properties > Hydrostatics |
The Hydrostatics command reports hydrostatic values for surfaces and polysurfaces.
Hydrostatic values include wetted surface area, waterline length, maximum waterline beam, water plane area, and center of floatation.

WaterLineElevation |
The water plane must always be horizontal in world coordinates. (This is a limitation of the command, not a statement of a physical principle.) Its location is defined by specifying the depth of the origin in world coordinates. |
Symmetric |
When only half of the model is given, the calculation results are doubled or adjusted as appropriate to represent the full model. |
Longitude |
The symmetry plane is either x=0 (when y is longitudinal) or y=0 (when x is longitudinal). The longitudinal direction (from bow to stern or front to back) must be either the direction of the x axis or the y axis. |
Hydrostatics
Volume under the water.
Centroid of the volume displacement.
Surface area under water.
Length at water line. The longitudinal bounding box extents of the water plane area.
Maximum beam at water line. The transverse bounding box extents of the water plane section.
Area of the cross section at the water plane.
Centroid of the water plane section These are the values for the whole model even if only a half model is given.
