Detailed Description

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

A 2D extension of the "contrast" initial state consisting of 4 different states separated at x = 0 and y = 0. Visually, this looks like:

   state 1  | state 2
   ---------|-----------
   state 3  | state 4

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 >.
