I am attempting to perform a similar simulation study as what was conducted in the article "Volume Conduction in an Anatomically Based Surface EMG Model" by Madeline Lowery et. al. (https://pubmed.ncbi.nlm.nih.gov/15605861/). In this article, they model the upper arm and then apply excitation electrodes and recording electrodes to the arm. The figure below is copied from their article. 

They state in their article that they used a "commercially available finite-element software package (EMAS 4.1,
Ansoft Corp., Pittsburgh, PA)." When searching for this same software program, I learned that Ansys bought out Ansoft many years ago, this article was published in 2004. 

So, I'm wondering which Ansys software package would best allow me to model a limb and apply surface electrodes to record signals in a similiar fashion as this study? Any insight would be greatly appreciated!

Hi Amber, 

If you look for only EM study, either HFSS or Maxwell would be applicable for this study. Given the very low frequency, Maxwell might be a better choice. It also depends on your specific objectives. If you need thermal or other physics, then we have other tools to couple with HFSS or Maxwell.

Hi Faezeh, 

Thanks for the insight! As of now I will just need EM, so I will start with Maxwell. If we decide to look into other physics later, I will look into the other tools needed for that. 

Thanks so much for your help!
