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 is adapted and the solution is recomputed with increased accuracy settings.

This parameter can be used to increase the PML thickness before the simulation is started. This can be useful if it is known that for the given simulation project, a posteriori PML refinements are likely. Multiple solution steps can be avoided.

Note

The actual PML thickness does not scale linearly with the thickness level. Typically the PML quality increases exponentially with the thickness level.
