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 >.
