Inverse Numerical Acoustics (L-Curve) scenario
The Inverse Numerical Acoustics (L-Curve) post-processing scenario lets you plot both the residual norms and tolerance values of the L-curve stacked in one view. In this view, you can also use the Select Value for Regularization probing mode option to extract tolerance values at each forcing frequency for a manual regularization in subsequent solutions. This pre-configured scenario is available for acoustic results in HDF5 file format.

For more information on extracting tolerance values, see Extract L-curve regularization values.
Selections for L-curve
You can choose to visualize the residual norms and tolerance values of the L-curve by:
Subcase, which lets you choose the subcase.
Frequency, which lets you choose the frequency.
Order Number, which lets you choose the order.Note: Appears when the Definition is set to Inverse Numerical Acoustics (L-Curve) - Order Cut.
Step through each selection
