capytaine.meshes.surface_integrals module

class capytaine.meshes.surface_integrals.SurfaceIntegralsMixin

Bases: ABC

property center_of_buoyancy: ndarray

Returns center of buoyancy of the mesh.

disp_mass(*, rho=1000) → float

property disp_volume: float

surface_integral(data, **kwargs)

Returns integral of given data along wet surface area.

Parameters:

data (np.ndarray) – Array of values at the quadrature points expected shape: (…, nb_faces, nb_quad_points)

property volume: float

Returns volume of the mesh.

property volumes: Tuple[float, float, float]

Returns volumes using x, y, z components of the mesh. Should be the same for a regular mesh.

property waterplane_area: float

Returns water plane area of the mesh.

property waterplane_center: None | ndarray

Returns water plane center of the mesh. Computed as (∫x/∫1, ∫y/∫1) on the water plane. Returns None if the mesh is full submerged.

waterplane_integral(data, **kwargs)

Returns integral of given data along water plane area.

Parameters:

data (np.ndarray) – Array of values at the quadrature points of the hull mesh. Expected shape: (…, nb_faces, nb_quad_points)

property wet_surface_area: float

Returns wet surface area.
