Detailed Description

The compressible Euler equations of gas dynamics. Specialized implementation for a subclass of barotropic equations of state where the pressure, internal energy and entropies are a function of the density. We use a specialied Riemann solver, entropy viscosity commutator, and limiter for this class of equations.

We have a (1 + dim) dimensional state space \([\rho, \textbf m]\), where \(\rho\) denotes the density, \(\textbf m\) is the momentum.

Member Function Documentation

view()

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

auto ryujin::EulerBarotropic::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.

void ryujin::EulerBarotropic::HyperbolicSystem::fill_precomputed_values ( const OfflineData< dim, ScalarNumber > &  offline_data, StateVector< ScalarNumber > &  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.

The precomputed values are computed with the selected barotropic equation of state on the host memory space. If MemorySpace is the default (device) memory space the state vector is thus temporarily transferred to the host memory space.
