Fluid simulations using Blender 2.46

Another item that interested me is fluid simulation. What I am trying to do is to do a scene where water is flowing from the spillway or powerhouse of the dam to the river downstream. I was looking for a software that can model fluid flow. Most of the popular 3D modelling and animation packages I looked at like 3DsMax, Maya and Softimage XSI do not have this built in feature. You still have to buy a plug-in called RealFlow from Next Limit Technologies. Each of these software packages cost between $5k to $10k without the plug-in for fluid simulation. To buy one of these to just be able to do the scene is not practical. The company I'm working in is into engineering design and consulting and not with the film industry.

I kept on Googling until I came across Blender http://www.blender.org/ . Not only is the software capable of fluid simulation but it is actually free. Before Blender all the modelling and rendering is done at the office. Now I can do it at home. Blender is 3D modelling, rendering and animation for the masses!

The first scene I did was a drop of grey colored liqid falling inside an invisible box.

The next one I did was this liquid flowing through an opening to an invisible pool.
