Detailed Description

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

A modification of the "contrast" initial state. Now, we have an initial state formed by a contrast of a given "left" and "right" primitive state where the "left" state is "inside" the radius, R, and the "right" state is outside.

Note

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

Todo:

Transform a nonzero initial velocity into a radial momentum scaling with 1 / r^(dim -1).

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 >.
