It's hardly surprising that they are extroardinarily complex. I don't think anything remotely simple that would be used to model fluid dynamics would be even marginally accurate. I mean fluid dynamics are nearly as complex as soap bubbles, and soap bubbles represent a category of the most computationally intensive physics ever.
A real question though, what level of comprehension of Fluid dynamics is needed to begin to use one of these programs? Thanks.
