Detailed Description

template<int dim, typename Number, typename MemorySpace>
class ryujin::EulerAEOS::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).

For a given (2+dim dimensional) state vector U, and a (normalized) "direction" n_ij, first compute the corresponding projected state in the corresponding 1D Riemann problem, and then compute and return the Riemann data [rho, u, p, a] (used in the approximative Riemann solver).
