I use LT-Spice from Linear Tech. It can do the things you want, and has a very
strong user group as well.

I am a from non-profit organisation. I don't access to these 3D/2D solvers.
i am simulating things with free simulation softwares like MC10. that's why i
am understaning thumb rules, when they will be applicable and limitations
