Detailed Description

template<class TSparseSpace, class TDenseSpace>
class Kratos::BossakRelaxationScalarScheme< TSparseSpace, TDenseSpace >

A scheme for steady and dynamic equations, using Bossak time integration.

It can be used for either first- or second-order time derivatives. Elements and conditions must provide a specialization of SchemeExtension via their data value container, which allows the scheme to operate independently of the variable arrangements in the element or condition.
