Interpolation

Ferrite.Interpolation — Type

Interpolation{ref_dim, ref_shape, order}()

Return an Interpolation on a ref_dim-dimensional reference shape (see AbstractRefShape) ref_shape and order order. 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{1,RefCube,1}
Lagrange{1,RefCube,2}
Lagrange{2,RefCube,1}
Lagrange{2,RefCube,2}
Lagrange{2,RefTetrahedron,1}
Lagrange{2,RefTetrahedron,2}
Lagrange{2,RefTetrahedron,3}
Lagrange{2,RefTetrahedron,4}
Lagrange{2,RefTetrahedron,5}
BubbleEnrichedLagrange{2,RefTetrahedron,1}
CrouzeixRaviart{2,1}
Lagrange{3,RefCube,1}
Lagrange{3,RefCube,2}
Lagrange{3,RefTetrahedron,1}
Lagrange{3,RefTetrahedron,2}
Lagrange{3,RefPrism,1}
Lagrange{3,RefPrism,2}
Serendipity{2,RefCube,2}
Serendipity{3,RefCube,2}

Examples

julia> ip = Lagrange{2,RefTetrahedron,2}()
Ferrite.Lagrange{2,Ferrite.RefTetrahedron,2}()
