Struct with options for this integrator

Public Members

double rtol = 1e-4

The desired relative tolerance used to control the integrator error.

double atol = 1e-8

The desired absolute tolerance used to control the integrator error.

km::Vec atol_vec

The desired absolute tolerance vector used to control the integrator error. This can be used rather than a scalar tolerance to set different values for different states.

long max_num_steps = 1e6

The maximum number of steps the solver can take before throwing a too much work error.

bool suppress_algebraric = false

Whether to suppress the local error test for algebraic variables. Recommended to enable for index 2/3 DAEs, but not for index 1 DAEs.

unsigned int anderson_accel = 0

Anderson acceleration used with the FixedPoint solver.

NLSOLVER nlsolver = NLSOLVER::FIXEDPOINT

The Nonlinear solver type to use.

METHOD method = METHOD::ADAMS

The solver method to use.
