There is an Enhanced Resonance Detection EM option available in the Advanced Options section of the EM Options page in the Circuit Settings dialog box in the project editor (Select Circuit ⇒ Settings, then click on "EM Options" in the sidebar menu of the Circuit Settings dialog box which appears). This option is useful when the circuit response includes one or more extremely narrowband resonances, a common occurrence with superconductor applications. When this option is enabled, ABS performs a full-wave discrete simulation at each detected resonance to obtain the highest level of accuracy possible in terms of magnitude and frequency. Be aware that this increased accuracy comes at the cost of increased processing time since it requires analysis at more discrete frequency points.
