I am solving a vector valued equation (mechanical equilibrium) using dealii's
matrix free infrastructure.
Although the library has several examples on how to apply neumann BC using
matrix free most are either scalar equations and using DG methods.
Is there an example of continuous vector valued problems using Matrix free
method ?
Ray -- Neumann boundary conditions lead to terms on the right hand side, which
you can build in the traditional way since no matrix is involved.
