Interpolation

Ferrite.Interpolation — Type

Interpolation{ref_shape, order}()

Abstract type for interpolations defined on ref_shape (see AbstractRefShape). order corresponds to the order of the interpolation. The interpolation is used to define shape functions to interpolate a function between nodes.

The following interpolations are implemented:

Lagrange{RefLine,1}
Lagrange{RefLine,2}
Lagrange{RefQuadrilateral,1}
Lagrange{RefQuadrilateral,2}
Lagrange{RefQuadrilateral,3}
Lagrange{RefTriangle,1}
Lagrange{RefTriangle,2}
Lagrange{RefTriangle,3}
Lagrange{RefTriangle,4}
Lagrange{RefTriangle,5}
BubbleEnrichedLagrange{RefTriangle,1}
CrouzeixRaviart{RefTriangle, 1}
Lagrange{RefHexahedron,1}
Lagrange{RefHexahedron,2}
Lagrange{RefTetrahedron,1}
Lagrange{RefTetrahedron,2}
Lagrange{RefPrism,1}
Lagrange{RefPrism,2}
Lagrange{RefPyramid,1}
Lagrange{RefPyramid,2}
Serendipity{RefQuadrilateral,2}
Serendipity{RefHexahedron,2}

Examples

julia> ip = Lagrange{RefTriangle, 2}()
Lagrange{RefTriangle, 2}()

julia> getnbasefunctions(ip)
