can't get cascading to work with geometry

[shawkins]

So I did some testing with cascading one simulator with another. I got it to work pretty well, so I merged my test file with a file that has the actual geometry that I'd like to use the cascading with and the simulation no longer works. Attached is the file I'm struggling with. Thanks for any help anyone can offer.

the reason is not only one
1. your velocity is not exported
2. the transferring source has no selected "affect velocity" option, this means the newly born liquid will have zero velocity, it must have the same velocity as the liquid in the first simulator, not zero.
3. the resolution of the first simulator is too low
beside this, i changed the scene to use better cascade concept. the old cascade example uses the first simulator as solid object and produces the new liquid on its surface. however if the first simulator is turned into non solid object and works as brush source with 100% discharge, the result is better because both the liquids are overlapped and there is big volume where the first simulator drives the second one.

Wow......I certainly didn't realize how much I was missing. I'll dig into it and try to understand your method better. I appreciate your help.

it's important the understand that there is no special cascade feature, this is just a trick entirely at user level. both the cascade methods are based on the ability to use one phoenix simulation as geometry in second simulator.

I see. Is there a trick to getting both simulations to run simultaneously? If I have one sim selected and started, I then add the other sim to the selection and both sim boxes are red. After some calculations, I notice that one of the sims turns back to green (unselected color) and the sim no longer is being calculated. Is there a specific method to getting both sims to be calculated from beginning to end?

no way to run simultaneously
first simulate the source simulator, after that start the second one
the red/green change is just because your pre simulated sequence is over
