Dual polynomial

Before running this example, you must install Bempp-cl:

pip3 install numba scipy meshio
pip3 install bempp-cl

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

import bempp_cl.api
grid = bempp_cl.api.shapes.regular_sphere(1)

# Create dual polynomial degree 0
element = bempp_cl.api.function_space(grid, "DUAL", 0)

# Create dual polynomial degree 1
element = bempp_cl.api.function_space(grid, "DUAL", 1)

# Create dual polynomial degree 1
element = bempp_cl.api.function_space(grid, "DUAL", 1)

# Create dual polynomial degree 1
element = bempp_cl.api.function_space(grid, "DUAL", 1)

Before running this example, you must install Symfem:

pip3 install symfem

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

import symfem

# Create dual polynomial degree 0 on a dual polygon(6)
element = symfem.create_element("dual polygon(6)", "dual", 0)

# Create dual polynomial degree 1 on a dual polygon(4)
element = symfem.create_element("dual polygon(4)", "dual", 1)

# Create dual polynomial degree 1 on a dual polygon(5)
element = symfem.create_element("dual polygon(5)", "dual", 1)

# Create dual polynomial degree 1 on a dual polygon(6)
element = symfem.create_element("dual polygon(6)", "dual", 1)
