warp.fem.ExplicitQuadrature#

class warp.fem.ExplicitQuadrature(domain, points, weights)[source]#

Quadrature using explicit per-cell points and weights.

The number of quadrature points per cell is assumed to be constant and deduced from the shape of the points and weights arrays. Quadrature points may be provided for either the whole geometry or just the domain’s elements.

Parameters:

  • domain (GeometryDomain) – Domain of definition of the quadrature formula

  • points (wp.array2d(dtype=Coords)) – 2d array of shape (domain.element_count(), points_per_cell) or (domain.geometry_element_count(), points_per_cell) containing the coordinates of each quadrature point.

  • weights (wp.array2d(dtype=float)) – 2d array of shape (domain.element_count(), points_per_cell) or (domain.geometry_element_count(), points_per_cell) containing the weight for each quadrature point.
