Steady State Callbacks

TerminateSteadyState(abstol = 1e-8, reltol = 1e-6, test = allDerivPass; min_t = nothing,
    wrap_test::Val = Val(true))

TerminateSteadyState can be used to solve the problem for the steady-state by running the solver until the derivatives of the problem converge to 0 or tspan[2] is reached. This is an alternative approach to root finding (see the Steady State Solvers section).

Arguments

• abstol and reltol are the absolute and relative tolerance, respectively. These tolerances may be specified as scalars or as arrays of the same length as the states of the problem.
• test represents the function that evaluates the condition for termination. The default condition is that all derivatives should become smaller than abstol or the states times reltol. The user can pass any other function to implement a different termination condition. Such function should take four arguments: integrator, abstol, reltol, and min_t.
• wrap_test can be set to Val(false), in which case test must have the definition test(u, t, integrator). Otherwise, test must have the definition test(integrator, abstol, reltol, min_t).

Keyword Arguments

• min_t specifies an optional minimum t before the steady state calculations are allowed to terminate.
