The Adaptive Frequency Sweep study type () is available as a predefined study for the Pressure Acoustics, Frequency Domain interface. The Adaptive Frequency Sweep study gives easy access to the asymptotic waveform evaluation (AWE) functionality available with a regular Frequency Domain study where it is located under the Study Extensions section.

In the Adaptive Frequency Sweep study the AWE expression type is set to User controlled as default. No Physics controlled expressions are defined for the acoustics interfaces. Enter the Asymptotic waveform evaluation (AWE) expressions in the table. The Relative tolerance can also be entered, the default value is 0.01.
