Detailed Description

Boundary linear form integrator for imposing non-zero Dirichlet boundary conditions, in a DG elasticity formulation. Specifically, the linear form is given by

alpha < u_D, (lambda div(v) I + mu (grad(v) + grad(v)^T)) . n > +

where u_D is the given Dirichlet data. The parameters alpha, kappa, lambda and mu, should match the parameters with the same names used in the bilinear form integrator, DGElasticityIntegrator.
