With the high-level Python and C++ interfaces to FEniCS, it is easy to get started, but FEniCS offers also powerful capabilities for more experienced programmers. FEniCS needs Python 3. Tkinter Display Text. The difference between range and xrange is that the range function returns a new list with numbers of that specified range, whereas xrange returns an iterator, which is more efficient. In UFC all elements are represented behind a single ufc::finite_element/dofmap interface. OpenFOAM is the leading leading free, open source software for computational fluid dynamics (CFD) [3].
