Detailed Description

template<bool visc = false>
template<int n_dim, int row_size>
class hexed::pde::Navier_stokes< visc >::Pde< n_dim, row_size >::Characteristics

Decomposes state vectors into characteristics which are eigenvectors of the Jacobian of the inviscid flux function. This is useful for characteristic-based boundary conditions.

shouldn't this have a 0.5*?
