Detailed Description

template<typename ScalarNumber = double, NASGRiemannSolverOptions options = NASGRiemannSolverOptions{}>
class ryujin::EulerAEOS::NASGRiemannSolver< ScalarNumber, options >

A fast approximative solver for the 1D Riemann problem with a Noble-Abel stiffened gas equation of state. The solver ensures that the estimate \(\lambda_{\text{max}}\) that is returned for the maximal wavespeed is a strict upper bound.

The solver is based on [2].

template<typename Number , typename MemorySpace = dealii::MemorySpace::Host>

auto ryujin::EulerAEOS::NASGRiemannSolver< ScalarNumber, options >::view ( ) const

inline

Return a view on the NASGRiemannSolver for a given choice of number type Number (which can be a scalar float, or double, as well as a VectorizedArray holding packed scalars). The optional MemorySpace template parameter selects whether the view is intended for the host or device memory space.
