Detailed Description

Represents an exact solution of a PDE.

ExactSolution represents an arbitrary user-specified function defined on a domain (mesh), typically an exact solution to a PDE. This can be used to compare an approximate solution with an exact solution (see DiffFilter).

Please note that the same functionality can be obtained by using Solution::set_exact(). This class is provided merely for convenience.
