hydrostatics.SolvedHull#

class hydrostatics.SolvedHull(hull, normal, waterline, rho, success, message)#

Result object for Hull.solve representing region of hull below waterplane. In addition to methods from SplitHull, also includes information about termination of Hull.solve. See SplitHull for more details.

Parameters:

hullHull: Base hull to split.
normalarray_like, shape (3,): Normal vector to plane. Will be normalized.
waterlinefloat: Constant term in plane equation.
rhofloat: Density of water in appropriate units. Default is 1., in which case displacements and moments are essentially in units of rho.
successbool: Whether the solver terminated successfully
messagestr: Details of solver termination.

Attributes:

hull: Base hull to split.
normal: Normal vector to plane.
waterline: Constant term in plane equation.
volume: Volume of region below waterplane.
center_of_buoyancy: Center of buoyancy (center of volume) of region below waterplane.
message: Details of solver termination.
success: Whether the solver terminated successfully.

__init__(hull, normal, waterline, rho, success, message)#

Methods

`plot`()	Plot 3D mesh and submerged view in Gmsh.
`righting_moment`()	Righting moment of region below waterline.

property center_of_buoyancy#

Center of buoyancy (center of volume) of region below waterplane.

Returns:

cobfloat: Center of buoyancy below waterplane.

property displacement#

Displacement of region below waterplane. If rho = 1.0, same as volume.

Returns:

displacementfloat: displacement of region below waterplane.

static finalize()#

property hull#
