Detailed Description

The compressible Euler equations of gas dynamics. Generalized implementation with a modified approximate Riemann solver for finding max wave speed, indicator, and limiter suitable for arbitrary equations of state.

We have a (2 + dim) dimensional state space \([\rho, \textbf m, E]\), where \(\rho\) denotes the density, \(\textbf m\) is the momentum, and \(E\) is the total energy.

void ryujin::EulerAEOS::HyperbolicSystem::fill_precomputed_values ( const OfflineData< dim, ScalarNumber > &  offline_data, typename HyperbolicSystemView< dim, ScalarNumber >::StateVector &  state_vector, const bool  skip_constrained_dofs = true  ) const

inline

Part of step 1 of the hyperbolic update step: Compute "precomputed values" and fill into the state vector.

Note

The method does not update the ghost range of the state vector. The precomputed part has to be synchronized by explicitly calling the update ghost values function.
