I'm not much aware of the Free EM Simulation tool. Maybe some other help you.
But Look out for Robert's youtube videos. He has many videos on this : https://www.youtube.com/channel/UCJQ...A8bgDmPlJlOJOA

We are talking about simulation tools here, it may help: https://designhelp.fedevel.com/forum...-analysis-tool

PS: I have not worked with free simulation tools, so I am not sure about them

Recently, in signal integrity journal, they had an article about low cost and free tools. Maybe this will be of interest if it doesn't completely answer your question.

Low-Cost and Free Tools Fit for an Engineer’s Personal Budget

If you are missing your engineering tools, or would like to build up your home lab, or want to finally work on that hobby electronics project you’ve put off for the last five years, or you want to introduce your kids to the thrill of measuring or simulating, now would be a good time to consider our list of free or very low-cost hardware and software simulation tools.

Hope this helps.
