Which could be the best FEA software for harmonic analysis of FSPM(flux switching permanent magnet) machine?

I want to do the simulation of FSPM machine on a FEA software. I am a beginner for FEA so suggest me from where should i start or from which software. Do i need to learn the software from classes or is it available from youtube or anything like this ? Detailed answer is appreciated. Thank you so much. I have uploaded the research paper, too.
