Detailed Description

The compressible Euler equations of gas dynamics. Specialized implementation for a polytropic gas equation.

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.

View

template<int dim, typename Number = double, typename MemorySpace = dealii::MemorySpace::Host>

using ryujin::Euler::HyperbolicSystem::View = HyperbolicSystemView<dim, Number, MemorySpace>

Alias for the view on the hyperbolic system for a given dimension dim, choice of number type Number, and memory space MemorySpace.

Member Function Documentation

view()

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

auto ryujin::Euler::HyperbolicSystem::view ( ) const

inline

Return a view on the Hyperbolic System 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. The optional MemorySpace template parameter selects whether the view is intended for the host or device memory space.

fill_precomputed_values()

template<typename MemorySpace , int dim, typename ScalarNumber >

void ryujin::Euler::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.
