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

\[ \alpha \langle u_D, (\lambda \mathrm{div}(v) I + \mu (\nabla v + \nabla v^{\mathrm{T}})) \cdot n \rangle + + \kappa \langle h^{-1} (\lambda + 2 \mu) u_D, v \rangle, \]

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.
