I hesitated with OPERA because I am a machine designer and they have not paid as much attention to machines. The others provide varying degrees of assistance to us "old time" motor designers..Ansoft trying the hardest lately with an analytical front end. Each has isses, mostly commercial / support / ease of use. In fact, the easiest to use was IES but the answers were inconsistent from model to model and did not agree with finite element. I could not recommend one over the other. I would say the solvers are all robust.Thanks for the feedback, Dave Squires |
