[?]how to show concrete pumping animation

Can anyone offer any suggestions on a good way to acheive the above? I have to produce an animation and one of the important elements is essentially concrete being pumped into a hole in the ground. I need to show a high slump consistancy and I have complete control over how I tell the story of what the product does.

I could make life easy and just fade a few frames each showing progressively more concrete going into the hole but it would be good to actually show it in motion for 10 seconds or so.

So I will use 3DS Max and/or AE however the concrete will be pumped out of my 3DS Max model. I can probably buy a plugin if required as long as it's reasonably low cost but the shedule will be quite tight so would need to be something with minimal learning curve.

Any advice would be appreciated.

I don't know enough about Max but if it has an equivalent to Maya's nParticle system (with liquid simulation settings) then you could use that and crank up the viscosity setting.

Realflow would be the ideal program, but it's really pricey. If this was a personal portfolio project and not for commercial use you could get the trial or cheaper student edition though.

Try doing a search in the 3ds Max sub-forum here and try some keywords like: "liquid particles" "sph" "viscous" etc.

Without knowing what it looks like to pump concrete, I would say try using Particle Flow with a blobmesh compound object.

This... plus put two different forces on the particles:

1) Over long distances the particles attract each other
2) In close proximity the particles repel each other

After a bit of playing with the input parameters, this will give you a fairly good approximation of concrete being poured.

Good luck!
