After a simulation with transparent boundary, an a posteriori estimator checks if the PML settings were sufficient to introduce no artificial truncation error to the solution due to too short PMLs. If necessary, the PML thickness is adapted and the solution is recomputed with increased accuracy settings.
This parameter can be set to limit the number of PML thickness increasement steps. Together with StartThicknessLevel this limits the maximum PML thickness level.
Note
The actual PML thickness does not scale linearly with the thickness level. Typically the PML quality increases exponentially with the thickness level.
