Detailed Description

template<int dim, typename Number, typename MemorySpace>
class ryujin::EulerBarotropic::WaveSpeedEstimatorView< dim, Number, MemorySpace >

A view of the WaveSpeedEstimator 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).
