Reference mappings for isogeometric analysis.
Reference mapping for isogeometric analysis based on Bezier extraction.
domain : IGDomain instance
The mapping domain.
cells : array
The mapping region cells. (All domain cells required.)
nurbs : NurbsPatch instance, optional
If given, the nurbs is used instead of domain.nurbs. The nurbs has to be obtained by degree elevation of domain.nurbs.
Return reference element geometry as a GeometryElement instance.
Get the mapping for given quadrature points and weights.
cmap : CMapping instance
The reference mapping.
Notes
Does not set total volume of the C mapping structure!
Get physical quadrature points corresponding to given reference Bezier element quadrature points.
qps : array
The physical quadrature points ordered element by element, i.e. with shape (n_el, n_qp, dim).
