I used to use CFD (computational fluid dynamics) softwares that were not very effective, but this one makes my work so much easier because it gives me more precision than other ones! It's also easy enough even if you don't have any scientific background at all. The interface could be better though; sometimes when adjusting something we need help from someone who knows what he/she doing since there are no labels or anything like that. There isn't really an advantage over others similar products out there now days except price which was lower back then compared with today prices. But still good product overall considering its' low cost nowadays. For example, solving problems about turbulent flows such as wind tunnel tests where accuracy matters most.
