Detailed Description

template<int dim, int n_components, typename Number>
class ExaDG::Elementwise::InverseMassPreconditioner< dim, n_components, Number >

This class implements an elementwise inverse mass preconditioner. Currently, this class can only be used if the inverse mass can be realized as a matrix-free operator evaluation available via utility functions in deal.II.
