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

$$\alpha ⟨u_D,(\lambda \mathrm{div}(v)I+\mu (\mathrm{\nabla }v+\mathrm{\nabla }{v}^{\mathrm{T}}))\cdot n⟩++\kappa ⟨h^{-1}(\lambda +2\mu )u_D,v⟩,$$

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.
