Detailed Description

template<int dim, typename Number>
class ryujin::ShallowWater::IndicatorView< dim, Number >

A view of the Indicator that makes the interface available for a given dimension dim and choice of number type Number (which can be a scalar float, or double, as well as a VectorizedArray holding packed scalars).
