Can anyone shed some light on why the fluid entering the second grid defies gravity?
further to this when I make a single grid that covers the full length the fluid runs down the creek bed for about a meter than just disappears!
every thing I have tried fails - the fluid just refuses to run any further!!!
Do you export velocity form the first simulator and did you check velocity on the phx source you use to transfer form one grid to the other?
yes to both of them. I followed the cascade example file. Would the velocity value have something to do with it? I have it set to .5 because I don’t want the fluid from the initial source flying out at high velocity.
Could be, is there any difference with just 1? Also, which version are you using?
I don’t want to hijack my own thread but since I can’t transfer the sim I made one long grid. It didn’t work so I went back to the shorter one and gradually increased the length, simming after each time I increased it. At cell 5cm x 750, y 200 z 60 it doesn’t work - about a third of the way down the grid the fluid just flows into another dimension like it is evaporating away. At x 500 it works fine.
Using v 2.2.0
Ha! Interesting, can we have the scene so we can debug it?
in the cascade example the discharge on the receiving grid is set to .001 - maybe that is the problem - mine was set to 1 - testing now
Discharge value makes no difference
x 650 also works
the cascade example is too old and the transfer source is in solid mode, that is worse than brush mode transfer. see this tutorial , it’s newer and more actual.
definitely - it’s very simplistic but I’ll zip it up and send it in an hour - cheers.
At 4:55 of part 2, adding objects in an interaction list I get a circular reference.
Did you change it to INCLUDE?
yes - changed to include
Then which object are you getting the circular reference message on?
i suppose you have the second simulator in the exclude list of the first one. this makes impossible to put the first simulator into the include list of the second one, because they reference on each other.
the correct setup is to put both the simulators in include list mode
- the first one interacts only with the bottle, wine source and initial fill up shape, the secion sim is not mentioned and there is no reference. the forst simulator must NOT interact with the second one, because if you try to tweak the simulation, the result of the previous simulation of the sim2 will disturb the simulation of sim1. i suppose this is not mentioned, because in the tutorial the second simulation is not existing during the setup of the first one and can’t produce problems.
- sim2 must interact with sim1, otherwise there will be no transfer. WARNING! this is different for phoenix versions below 2.2.
so, in few words, both the simulators must be in the same mode, exclude or include, to prevent the circular reference. i prefer the include list, because in scenes with multiple simulators each sim has its own object set, and it’s good to be mentioned explicitly.
that is probably what happened. I don’t have the file any more to check but I tried it from scratch this morning and didn’t get the circular error.
