The Compute Minimum and Maximum Pressure subfeature can be added to the Nonlinear Pressure Acoustics, Time Explicit Model as either a domain or a boundary feature. The minimum and maximum value of the pressure, over time and space, will be computed on the selected entity. It will create two variables nate.p_min and nate.p_max, these can be used in results to, for example, evaluate the size of a focal zone.
