pylot-bem
Write side of the hydrodynamic database: meshing, in-process Capytaine solving, assembly, a command line and a standalone application.
Pylot is a pylot_db.Library — it adds meshing and solving to the same
object, so a file written here opens as a plain Library on a machine with no
BEM solver installed. That split is the point, and a test enforces it.
Build a library
import numpy as np
from pylot_bem import Pylot, SolveSettings
d = Pylot.create_new("tanker.pylot", "tanker.stl", "stern, centerline, keel",
is_xz_symmetric=True)
condition = d.create_condition(z_origin=-12.0, condition_id="design")
mesh = d.create_mesh(condition, pct=2.0)
result = d.run_solve(mesh, SolveSettings(
omegas=[2 * np.pi / T for T in (12.0, 16.0, 20.0)],
wave_directions=[0.0, 45.0, 90.0, 135.0, 180.0],
))
print(d.validate() or "clean")
d.close()
Reading one back is pylot-db, which
this package depends on and which needs no solver.
The application
uv run pylot-app
A window for building and inspecting libraries: the tree, a 3D view in
diffraction space, property panes, and tabs for Results, Databases, Inspect,
Match and Validation. docs/manual.md walks through it screen
by screen and assumes you already know Capytaine.
