Solution Method Specifies the method used to solve the differential
equations.
• RK — Runge-Kutta method. For information about the
algorithm used for this method, refer to the Technical
Reference module.
• EULER — Euler method.
• The method lets you choose either greater accuracy or
speed. Typically, RK is more accurate than EULER but
takes longer to find the solution.
