sfepy.discrete.fem.mappings module
Finite element reference mappings.
-
class
sfepy.discrete.fem.mappings.FEMapping(coors, conn, poly_space=None, gel=None, order=1)[source]
Base class for finite element mappings.
-
get_base(coors, diff=False)[source]
Get base functions or their gradient evaluated in given
coordinates.
-
get_geometry()[source]
Return reference element geometry as a GeometryElement instance.
-
get_physical_qps(qp_coors)[source]
Get physical quadrature points corresponding to given reference
element quadrature points.
| Returns: | qps : array
The physical quadrature points ordered element by element,
i.e. with shape (n_el, n_qp, dim).
