quartic2d.Interaction.set_method#

Interaction.set_method(method, *, n=None, bias=None, subdivisions=None, N=None, h=None)#

Select the interaction quadrature and recompute V.

Parameters:

  • method ({'fftlog', 'trapezoid', 'simpson', 'gl4', 'gl8', 'ogata'}) – Method used for the final radial interaction integrals.

  • n (int or None, optional) – FFTLog sequence length. Used only by method='fftlog'.

  • bias (float or None, optional) – FFTLog power-law bias. Used only by method='fftlog'.

  • subdivisions (int or None, optional) – Finite-grid refinement used by trapezoid, simpson, gl4, and gl8.

  • N (int or None, optional) – Ogata node count. Used only by method='ogata'.

  • h (float or None, optional) – Positive Ogata resolution parameter. Used only by method='ogata'.

Returns:

This instance after recomputing V and harmonic-pair contributions.

Return type:

Interaction

Raises:

  • ValueError – If method is unsupported or a supplied numerical parameter is invalid.

  • ImportError – If method='ogata' and the optional hankel dependency is unavailable.

Notes

Method-specific parameters that are not supplied retain their current values. Changing the method clears cached Ogata data and any attached interaction convergence record.
