Automatic PML Creation in Ansoft HFSS

Dear All,

I read in an Ansoft document about PML that:

- the "Uniform Layer Thickness" should be set to be lamda/10 of the lowest frequency to be solved for (page 7 of the doc attached). Can anybody explain me which minimun frequency it is in concern here? It is the start frequency for the analysis or the minimun frequency set in the PML Wizard?

- should the minimun frequency set in the PML Wizard (page 9 of the doc attached) match the minimun frequency set in the Analysis set up (Sweep set up) of the project?

Thanks,

EL
