| Problem | Likely cause | Fix | |---------|--------------|-----| | Simulation loop fails to run | Missing ODE solver | Right-click loop → → choose RK45 or Variable Step | | Discrete model unstable | Sampling time mismatch | Match controller and plant sample times (e.g., 0.01s) | | Module not showing in palette | License not activated | Run NI License Manager, activate module | | Slow simulation | Stiff system | Use Stiff solver (e.g., Gear’s method) |
