Detailed Description

template<typename Description, int dim, typename Number>
class ryujin::EulerInitialStates::ThreeStateContrast< Description, dim, Number >

An initial state formed by two contrasts of given "left", "middle" and "right" primitive states. The user defines the lengths of the left and middle regions. The rest of the domain is populated with the right region. This initial state (default values) can be used to replicate the classical Woodward-Colella colliding blast wave problem described in [16]

Note

The t argument is ignored. This class always returns the initial configuration.

inlinefinalvirtual

Given a position point returns the corresponding (conserved) initial state. The function is used to interpolate initial values and enforce Dirichlet boundary conditions. For the latter, the function signature has an additional parameter t denoting the current time to allow for time-dependent (in-flow) Dirichlet data.

Implements ryujin::InitialState< Description, dim, Number >.
