CST microwave studio; Steady State Energy not met Warning

What is the warning: "Steady State Energy Criterion Not met. Maximum pulse widths simulated. Solver Stopped" mean? Any input is welcomed
Thanks

Probably you're analyzing a high-resonant structure so the energy was still entrapped in the structure when the solver stopped.
Try to go to: "Transient Solver--->Specials---->Steady State" and set a higher value in the box relative to "Maximum number of pulses".
If the simulation was too slow, you could try to use the AR-filtering too or instead the frequency solver.

Thank you. Just curious but do you work with CST at your job?
