Kong–Mulder–Veldhuizen

Before trying this example, you must install FIAT:

pip3 install git+https://github.com/firedrakeproject/fiat.git

This element can then be created with the following lines of Python:

import FIAT

# Create Kong-Mulder-Veldhuizen order 1
element = FIAT.KongMulderVeldhuizen(FIAT.ufc_cell("triangle"), 1)

# Create Kong-Mulder-Veldhuizen order 3
element = FIAT.KongMulderVeldhuizen(FIAT.ufc_cell("triangle"), 3)

# Create Kong-Mulder-Veldhuizen order 1
element = FIAT.KongMulderVeldhuizen(FIAT.ufc_cell("tetrahedron"), 1)

Before trying this example, you must install Symfem:

pip3 install symfem

This element can then be created with the following lines of Python:

import symfem

# Create Kong-Mulder-Veldhuizen order 1 on a triangle
element = symfem.create_element("triangle", "KMV", 1)

# Create Kong-Mulder-Veldhuizen order 3 on a triangle
element = symfem.create_element("triangle", "KMV", 3)

# Create Kong-Mulder-Veldhuizen order 1 on a tetrahedron
element = symfem.create_element("tetrahedron", "KMV", 1)

Before trying this example, you must install (legacy) UFL:

pip3 install setuptools
pip3 install fenics-ufl-legacy

This element can then be created with the following lines of Python:

import ufl_legacy

# Create Kong-Mulder-Veldhuizen order 1 on a triangle
element = ufl_legacy.FiniteElement("KMV", "triangle", 1)

# Create Kong-Mulder-Veldhuizen order 3 on a triangle
element = ufl_legacy.FiniteElement("KMV", "triangle", 3)

# Create Kong-Mulder-Veldhuizen order 1 on a tetrahedron
element = ufl_legacy.FiniteElement("KMV", "tetrahedron", 1)
