reference_element(9)
NAME
reference_element - reference element
SYNOPSYS
The reference_element class defines all supported types of geometrical
elements in one, two and three dimensions. The set of supported elements are designate by a letter
p point (dimension 0)
e edge (dimension 1)
t triangle(dimension 2)
q quadrangle(dimension 2)
T tetrahedron(dimension 3)
P prism(dimension 3)
H hexaedron(dimension 3)
