Detailed Description

template<size_t Dim, typename TensorTags>
class amr::Criteria::Loehner< Dim, TensorTags >

h-refine the grid based on a smoothness indicator

The smoothness indicator used here is based on the magnitude of second derivatives. See amr::Criteria::loehner_smoothness_indicator for details and caveats.
