◆ values_to_be_pinned_on_outer_pml_boundary()

pure virtual |
Pure virtual function in which we have to specify the values to be pinned (and set to zero) on the outer edge of the pml layer. This is usually all of the nodal values (values 0 and 1 (real and imag part) for Helmholtz; values 0,1,2 and 3 (real and imag part of x- and y-displacement for 2D time-harmonic linear elasticity; etc.). Vector must be resized internally!
Implemented in oomph::PMLTimeHarmonicLinearElasticityEquationsBase< DIM >, oomph::PMLHelmholtzEquations< DIM >, and oomph::PMLFourierDecomposedHelmholtzEquations.
