Import or export Nemoh.cal files for backward compatibility with Nemoh 2.

capytaine.io.legacy.export_as_Nemoh_directory(problem, directory_name, omega_range=None)[source]

Export radiation problems as Nemoh 2.0 directory (experimental).

TODO: Diffraction problem.

Parameters:

  • problem (RadiationProblem) – the problem that should be exported

  • directory_name (string) – path to the directory

  • omega_range (list of float or array of float, optional) – the exported problem will be set up with the following linear range: linspace(min(omega_range), max(omega_range), len(omega_range))

capytaine.io.legacy.export_hydrostatics(hydrostatics_directory, bodies)[source]

Export rigid body hydrostatics in Nemoh’s format (KH.dat and Hydrostatics.dat).

Parameters:

  • hydrostatics_directory (string) – Path to the directory in which the data will be written (two files per body)

  • bodies (FloatingBody or list of FloatingBody) – The body or the list of bodies. Each body is assumed to be a single rigid body with 6 dofs. Each FloatingBody object is expected to have an inertia_matrix and a hydrostatic_stiffness parameter.

Return type:

None

capytaine.io.legacy.import_cal_file(filepath)[source]
