Detailed Description

template<class PrecondElasticityBlock>
class Opm::Elasticity::MortarSchurPre< PrecondElasticityBlock >

This implements a Schur-decomposition based preconditioner for the mortar-elasticity system [A B] [B' ]

The preconditioner is [Apre B] [ P] Here Apre is some preconditioner for A and P some preconditioner for S = B^TA^-1B !
