pyopensn.aquad.SLDFEsqQuadrature2DXY

class pyopensn.aquad.SLDFEsqQuadrature2DXY

Two-dimensional variant of the piecewise-linear finite element quadrature.

This quadrature is created from the 3D SLDFEsq set by removing directions with negative xi.

LocallyRefine(self: pyopensn.aquad.SLDFEsqQuadrature2DXY, ref_dir: pyopensn.math.Vector3, cone_size: float, dir_as_plane_normal: bool = False) → None

Locally refines the cells.

Parameters:

ref_dir (pyopensn.math.Vector3) – Reference direction \(\vec{r}\).
cone_size (float) – Cone size (in radians) \(\theta\).
dir_as_plane_normal (bool, default=False) – If true, interpret SQ-splitting as when \(|\omega \cdot \vec{r}| < \sin(\theta)\). Otherwise, SQs will be split if \(\omega \cdot \vec{r} > \cos(\theta)\).

PrintQuadratureToFile(self: pyopensn.aquad.SLDFEsqQuadrature2DXY, file_base: str) → None

Prints the quadrature to file.

Generates a 2D SLDFEsq quadrature by removing directions with negative xi.

Parameters:

level (int) – Number of subdivisions of the inscribed cube.
scattering_order (int) – Maximum scattering order supported by the angular quadrature.
