EM simulatror series

dear all~
where can I find the EM simulator series ??
I want to compare the characteristics for each simulator.

I think It's a hard think. Most of the comparations (official) are made for a EM development, so I think that you can find the forum (this and others) for peoble opinions and experiencies.

for example:
