wecopttool.add_linear_friction
- add_linear_friction(bem_data, friction=None)[source]
Add linear friction to BEM data.
Returns the Dataset with the additional information added.
- Parameters:
bem_data (Dataset) – Linear hydrodynamic coefficients obtained using the boundary element method (BEM) code Capytaine, with sign convention corrected. Also includes inertia and hydrostatic stiffness.
friction (ArrayLike | None) – Linear friction, in addition to radiation damping, of size
(ndof, ndof)
.None
if included inbem_data
or to set to zero.
