hydrostatics.SplitHull#
- class hydrostatics.SplitHull(hull, normal, waterline, rho=1.0)#
Split hull along a plane defined by
normal.dot(x) = waterline.- 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.
- Attributes:
- __init__(hull, normal, waterline, rho=1.0)#
Methods
plot()Plot 3D mesh and submerged view in Gmsh.
