TR-BDF2

Implicit multistep solver implementation of TR-BDF2, which is an implicit Runge-Kutta formula with a first stage that is a trapezoidal rule step and a second stage that is a backward differentiation formula of second order.

Applicable for stiff problems of low accuracy.

Applicable solver settings:

  • Absolute tolerance
  • Relative tolerance
  • Initial step size
  • Max step size
  • Min step size
  • Refine
  • Limit data points to last
  • Norm Control
  • Allowed step size violations
  • Enable saturation
  • LU decomposition matrix format
