Detailed Description

This class represents nonlinear transient transport problem. The problem can be growing/decreasing, signalized by flag "changingproblemsize" in the problem description. The solution is stored in UnknownsField, which can obtain/ project solution from/to DOFs (nodes). If the problem keeps the same equation numbers, solution is taken from UnknownsField without any projection, which is more efficient. See the matlibmanual for solution strategy of balance equations and the solution algorithm.

Todo: Documentation errors (there is no "UnknownsField" used here).
