Nonsplit PML (NPML) for elastics

The nonsplit PML for elastic implementation is

$\begin{equation*}\left\{ \begin{split}\rho\frac{\partial v_x}{\partial t} &= (\f... ...l v_z}{\partial z}-\mu\Psi_{zx}-\mu\Psi_{xz}\\ \end{split}\right.\end{equation*}$

(27)

where the auxiliary variables are governed via the following relation

$\begin{equation*}\left\{ \begin{split}\frac{\partial \Omega_{xx}}{\partial t}+d(... ...Psi_{zz}=d(z)\frac{\partial v_z}{\partial z}\\ \end{split}\right.\end{equation*}$
