real flow fluid dynamic software
 

this software allows you to create fluid dynamics and you can get it on a 30 trial. looks like it could be a useful tool for testing water block design.

It's for special effects for 3DSMAx, MAYA, etc... It's not designed to do real CFD and fluids dynamics approach :D

Then what can we use?

Fluent 6.1, CFX 5.5 , StarCD, CFD++ or others and again other softs to mesh and do post-processing on data. None of them is free :D and they are really really complex...

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.

many will start to become proficient in it as part of their MS coursework for their thesis

but you will really only start to use it 'usefully' after being trained by your employer
many disciplines involved to pull a CFD based 'design' together

imNho

Seconded. My former place of employment had around 100 degreed engineers on staff with three or four that lived and breathed ANSYS 40+ hours a week. Each toted an MS degree and fifteen+ years on the job. There was no substitute to having them on hand the first time (or three or four times) you worked through a given style of problem. Back then most of my stuff revolved around stress analysis, dynamic responses, and deflected shapes based on force and thermal loads. A couple of guys used CFD to model airflows.

Alas, this was all before my addiction to computer cooling began. . .

thanks guys some usefull info there.
I am still intersted in the realflow so i will get the trial version just to have a look.
