Features¶
Capytaine is based on
Nemoh’s Fortran core routines for the computation of the Green function,
meshmagick for the manipulation of meshes,
and various tools from the Python scientific ecosystem.
For users, it can be seen as a Python 3.7 (or higher) interface to Nemoh. Since most of the code has been rewritten, it can be used by developers as a more concise and better documented version of Nemoh.
Below some features of the latest version (version 2.0) of Capytaine are listed.
Main features¶
Computation of the added masses, radiation dampings, diffraction forces and Froude-Krylov forces for rigid bodies or for bodies with any arbitrary degrees of freedom.
Python object oriented API.
OpenMP parallelization.
Direct or iterative linear system solver.
Various input mesh formats supported via meshmagick.
Output in legacy Nemoh Tecplot format or NetCDF format.
Computation of the free surface elevation and the Kochin function.
3D animations of the body motion and the free surface elevation.
A cleaner code with unit tests, meaningful variable names, more comments, no Fortran 77, no global variables and no error message in French.
Single or double precision floating-point numbers.
Possibility to plug-in other implementations of the Green function
Binaries distributed via conda-forge.
Experimental features¶
Computation of the hydrostatic stiffness and rigid body inertia. Non-neutrally buoyant bodies are partially supported.
Computation of the impedance matrix and the Response Amplitude Operators (RAO).
Input via legacy
Nemoh.cal
files.Hierarchical matrices with low-rank blocks for faster simulations.
Toeplitz matrices for faster simulations for floating bodies with local symmetries or for regular arrays of identical floating bodies.
Higher order quadratures for more precise integration of the Green function.
