Try out different Solver settings by opening the pressing "Ctrl+E" and opening the "Model Settings" pane. Select a more "stiff solver" such as ode15s, ode23s; reduce the relative error tolerance; reduce the maximum and minimum step size. Al...

If the solver sets its own time-step, and a fortiori if it is auto-adaptive (like ode45), the solver function is called once to generate the total number Nbuf of samples in one audio buffer. This is implemented as [~,Xts] = ode45(@(t,Xt) VanDerPol5_odefun(... Xt,t,mu,nu0,...
Duo E6700 (2.66 GHz) that was running xPC Target™. The maximum percentage of a step spent in simulation execution was less than 18%, leaving a wide safety margin for processing I/O and other tasks. The average percentage spent in simulation execution was 3.9%, and the minimum...
