double anderson_damping = 1

Anderson damping in (0, 1] used for implicit integrators with fixed-point solves.

This is used to potentially speed up internal iterations by reusing past iterates (within the same time step). A value of 1 indicates no damping, and smaller values imply a “stronger” damping.

int anderson_length = 0

Number of past iterates to consider with Anderson acceleration.

unsigned int max_nl_iters = 3

Maximum number of nonlinear iterations before we try a smaller step size.

bool use_jacobian = false

set to true to have the integrator use Jacobians (experimental)
