Does anyone have any information regarding the rational streching of PML in COMSOL? I am trying to find out how COMSOL determines parameters for rational stretching.Mon, 21 Oct 2013 16:58:04 +000037237.1382374684.109163Re: PML Coordinate Stretching

For rational PML stretching option, the equations obtained from the model is different from the one provided in reference guides. Can someone please explain how comsol uses rational stretching?Thu, 26 Sep 2013 15:51:02 +000037237.1380210662.108181Re: PML Coordinate Stretching

So far I have been successful in getting results using rational strecthing. Whenever I use polynomial stretching, it gives me erroneous results. What is the basic difference between these two?Wed, 24 Jul 2013 23:46:59 +000037237.1374709619.106055Re: PML Coordinate Stretching

I guess that's because in that domain only waves propagating in the Y direction need to be absorbed.Wed, 26 Jun 2013 23:22:50 +000037237.1372288970.104789PML Coordinate Stretching

When I see the equation mode, PML in one of the direction (mapped coordinate e.g. y direction) is stretched to complex number but another remains only real for my 2D analysis, why is that?<br />
<br />
Also does PML work for eigenfrequency analysis?<br />
<br />
Any help would be appreciated. Thanks.<br />
