Hello there, I am trying to define a perfectly matched layer property in Abaqus for the model below. I keep running into errors saying "element # is not fully located in the prescribed PML domain". The model has a beam located between 1 and 4, then radiating into the acoustic domain.

I found a sample input file in the link below but the acoustic domain is defined differently from my model. https://docs.software.vt.edu/abaqusv2022/English/SIMACAEVERRefMap/simaver-c-perfectlymatchedlayers.htm

Please advise on how I should set the coordinates for the diagonals of the PML regions in my model in the figure below. Numbers are included at certain points just in case you want to use them as reference points for explaining how to set coordinates for the diagonals

Thank you in advance
