Detailed Description

template<int dim, int n_equations>
class ExactSolution< dim, n_equations >

Alternative vector-valued exact-solution class.

Like Solution, this class derives from dealii::Function<dim> with n_equations components, but it implements a different analytic expression

• first component: \(\sin(\pi x)\sin(\pi y)\),
• second component: \(0\).

ExactSolution is currently only used in test variants that are commented out in step-6.cc. It is kept here so that switching between manufactured solutions is a one-line change.

Template Parameters

dim	Spatial dimension (the implementation assumes 2).
n_equations	Number of vector components (set to 2).
