Simple shallow pool??

[peterguthrie]

can phoenix do something like this? http://s22.postimg.org/o51f4l5up/LA_030.jpg

I did this using 3dsmax 2009 reactor but cant seem to produce anything similar using phoenix.

It just needs to be a simple pool with a few cylindrical objects in the way and a light wind making the water move. How would I go about doing this?

the wind force can't produce waves on the liquid surface, it will make all the water to move like a river.
i suppose you need just the surface waves interaction with the cylinders and the walls? well, we were planing to add ability to simulate 2d surface waves, it's much simpler and faster than the volumetric simulation, but the need of such simulation seems to be very rare. i'm afraid it's impossible now.

you could do it maybe by making the scale of the objects decrease in size then go back up to normal, so they pulse slightly. if you want it to only go in one direction to simulate wind, use an ffd to do it only on one side.

I did a quick test and it doesnt work in forward transfer mode, the open water becomes very unstable and starts to vibrate until a ripple hits it - using the flip solver i cant get the scale change to produce any ripples. using classic works great though.
They run out of momentum very quickly though - ivaylo do you have any suggestions to preserve the energy of them?



Thanks for giving me the idea for this, going to use it in the future. I think with more than 10 minutes on it it could work.

as i understand he needs not the cylinders to produce the waves, but the wind, and the cylinders just to be obstacles.

yeah but wouldn't it look pretty much the same after it's been simulating for a while and the ripples start to bounce back?

[peterguthrie]

doesnt necessarily need to be generated by wind - in the reactor version i just generated movement by dropping a ball into it, then left it running and after a while got really nice looking water movements. looks like a good solution Neilg

with phoenix you will need too big simulator for this, even if the z size is as small as possible. the simulation is 3d that is a big disadvantage.
