◆ equilibria

std::vector<std::map<std::string, std::string> > line::fluid::FluidJacobian::equilibria

Solutions of f(x) = 0, each a variable -> expression map.

EMPTY IS NOT AN ASSERTION THAT NONE EXIST. The backend returns what it solves in closed form, and a system beyond it answers with nothing; that is a limit of the solve. has_equilibria separates "asked and answered with none" from "never asked".
