WebElement families¶. UFL predefines a set of names of known element families. When defining a finite element below, the argument family is a string and its possible values include "Lagrange" or "CG", representing standard scalar Lagrange finite elements (continuous piecewise polynomial functions); "Discontinuous Lagrange" or "DG", representing scalar … http://www.fenicsdirect.com/
