Water depth for Capytaine

I'm not sure 0 is a good default value for the water depth in Capytaine.

I don't mind using the "negative = infinity" convention used in other solver, but given the line

waterdepth = float(self.ui.teWaterdepth.text())

then entering infinity or inf would give float('inf') which is the actual floating point representation of infinity.

add a "select work-dir" option

Save symmetry to .dhyd files

in mafredo:

 # try read info
        try:
            with xr.open_dataset(filename, group="info", engine="netcdf4") as ds:
                isym = ds["symmetry"]
                R.symmetry = Symmetry(isym)
        except:

Saving `diffraction_result`?

Out of curiosity, what is the point of the DiffractionResult object included in the dataset there?

dataset['diffraction_result'] = diffraction_result

Error writing Capytaine data to hyddb1

When running the standalone executable linked in capytaine/capytaine#372, I get the following error message in the console:

Please add .stp (STEP) via CadQuery

pip install cadquery

import cadquery as cq
from cadquery import exporters

result = cq.importers.importStep(r"C:\data\hdgphm0150.stp")
exporters.export(result,
fname = r"c:\data\exported.stl",
angularTolerance = 0.9,
tolerance =10)

GHS import - artifacts when merging close matching shapes

When the shapes "nearly" fit, artifacts are created on the intersection.
For example when attaching skegs to a hull:

Auto close holes in meshes by re-constructing frames from shape

Idea:

• cut a provided shape into frames using vtk cutter
• pull concave hull around the frames using alpha shapes
• reconstruct hull from frames
