`CollocationBasisValues`(points, V, nderiv)
`QuadratureGrid`(V, *, nquads[, axis, ext, ...])	Quadrature points and weights local to the current MPI process.

class QuadratureGrid(V, *, nquads, axis=None, ext=None, trial_space=None)[source]#

Bases: object

Quadrature points and weights local to the current MPI process.

Local quadrature grid for assemblying functionals, linear forms, and bilinear forms. A Gauss-Legendre quadrature grid is assumed.

Parameters:

VFemSpace: Finite element space from which we extract the breakpoints.
axisint, optional: If given, the grid is constructed on the given boundary (axis, ext).
ext{-1, +1}, optional: If given, the grid is constructed on the given boundary (axis, ext).
trial_spaceFemSpace, optional: TBD.
nquadslist or tuple of int: Number of quadrature points along each direction.

property local_element_start#: Local index of first element owned by process.

property local_element_end#: Local index of last element owned by process.

class BasisValues(V, *, nderiv, nquads, trial=False, grid=None)[source]#

Bases: object

Basis values and spans for a given FEM space over a quadrature grid.

Parameters:

VFemSpace: The space that contains the basis values and the spans.
nderivint: The maximum number of derivatives needed for the basis values.
trialbool, optional: The trial parameter indicates if the FemSpace represents the trial space or the test space.
gridQuadratureGrid, optional: Needed for the basis values on the boundary to indicate the boundary over an axis.
nquadslist or tuple of int: Number of quadrature points along each direction.
