Is simulation possible in NX 8?

yes, all simulations are possible in nx 8 as long as you have the license

Of course! In fact, here's a video of a simulation i did using NX 7.5 (a boring 1min 39 sec video, but this is just to show you that the simulation work)..then i open it run the simulation on NX 8.0 (see the jpeg) and it worked well...

yes,FEA analysis uses nastran solver,motion simulation also there,also topology optimization

thanks everyone in GRAB CAD
