                                                    Hi 
For me, the most stable and best functionality v3 is the 3.5a. The V4 was a major change in the GUI approach ans a reorganising of the physics definition, personally I find the current 4.2a at least as stable as the 3.5a, and much nicer and easier to build models, to mesh them and sovle them. Not to say many more functionalities, and physics combinations. 
There is a rather hughe difference in the user-software interface between v3 and v4. Personally I would NOT advise anybody to learn 3.5 if he had the opportunity to use v4

Good luck

                                                    Thank you very much. I myself first started with 3.4/3.5 version and directly jumped to the 4 versions and was quite impressed of the way to determine the physics. And i wasn't sure is it just the smoothnees of the user iterface that is changed or also something in the way of calculation the problems. Obviously not.

the equations underneat are the same, the maths too (from my knowledge) but variables naming and approaches has changed, so if you are used to 3.5 do expect a few weeks to learn the new way. But once you know the "new" way, you will rapidly ask yourself why go back ;)
