Detailed Description

Integrator for the linear elasticity form: a(u,v) = (lambda div(u), div(v)) + (2 mu e(u), e(v)), where e(v) = (1/2) (grad(v) + grad(v)^T). This is a 'Vector' integrator, i.e. defined for FE spaces using multiple copies of a scalar FE space.

With this constructor lambda = q_l * m and mu = q_m * m; if dim * q_l + 2 * q_m = 0 then trace(sigma) = 0.
