TīmeklisTo acces individual subfunctions, FEniCS provides the function split. There exist two different versions of this function, the first is called via FEniCS package [24]: u, p = fe.split(sol) which returns some kind of link on subspace. Usually it is sufficient e.g. for plotting for example, but cannot be used for some operations with subfunctions.
