these are the answers based on your questions above:
1. You can use Initial fill up option to fill the container up to a certain level. You can find this in Dynamics roll-out in Max or Liquid roll-out in Maya.
2. There are two ways for this effect - make negative gravity or make zero gravity and add a Body force helper.
3. For directional force (like the wind), you can use a Phoenix Plain force. It’s easy to navigate the direction and its intensity. Also, you can add a Phoenix Turbulence force for creating some random swirling.
4. Every solid object can affect the liquid by default unless it’s added in an exclusion list or it’s converted to “non-solid” from Phoenix object properties menu.
Hi George Barzinski.
I will really appreciate that.
BTW I work with MaYa 2017.
I played in these days with your tips and I get something interesting.
My only problem is the wind effect.
The Plain Force somehow doesnt work will I have a Body Force Helper.
I will upload a screenshot to the result I have at the moment.
The ball is moving from the left to right and as you can see the water follows the ball direction and suppose the water to fly in the other direction.
Do you know why the simulation take too long?
EDIT: Im using 2 steps for the simulation BTW.
20 frames with 16 000 000 particles takes like a 4 minutes on a:
Windows 10
nVidia Quadro 4000
Intel Xeon E5-2683 v4 @ 2.10 GHz
you can try to decrease Motion Inertia parameter in Dynamics roll-out. This will make the water less affected by the motion of the ball and combining this with Body Force or Plain Force with enough strength should do the trick. I think your simulation time is pretty good for a grid with 16 000 000 cells.
Nice mate! Great result. Optionally you can smooth the liquid a little bit more with Mesh Smoothness parameter in Rendering -->Mesh roll-out menu. Also, you can share your final result in our facebook group and exchange some knowledge with our community: https://www.facebook.com/groups/233735903483447/
Hi George,
May I ask you what kind of computer should I have to make the simulation calculate faster?
My specs:
Dynamic simulation: 2 steps
20 frames with 16 000 000 particles takes like a 3 minutes on a:
Windows 10
nVidia Quadro 4000
Intel Xeon E5-2683 v4 @ 2.10 GHz
Is there anything I can do to get the particles calculate faster?
In your videos the simulation runs extremely fast.
I know you have a much better computer, but what kind of computer?
Firstable I want to notice that some of our simulations in video tuts are played faster and there’s also a sign in the right bottom corner which indicated that. That’s because no body would watch a tutorial with 30 min simulation in it It’s boring.
So, how to make your simulation faster? In your case Grid Resolution (the cell count) and Steps per Frame (SPF) are the parameters which will make your sim faster or slower BUT also, the final result depends on them. That’s really important. For tests you can make the resolution about 2 - 3 million cells and reduce SPF to 1. The result would be a much faster simulation but not so detailed but it’s a test after all. Higher SPF = smoother liquid. There’s a video example of this parameter.
Now I understand does 2 ►► on the Chaos Group videos.
I didnt know what that means. I know it is forward, but not speed altered. LOL!
Thank you for your support. Love Chaos Group, V-Ray and Phoenix for MaYa !
EDIT:
Hi George again.
Could you please move the STEPS of the Simulation information a little bit more to the bottom after the View Port Info from MaYa?
I know. Nobody use that info, but unfortunatelly I need to use.
Is extremely hard to see which step is doing the simulation.
Does this changes are applied to the download file under the Chaos Group page?
I tried to send you a PM, but you choose to not received any messsage

Hi George!
How you doing?
I just download the last version of PFD from the normal Chaos Group webpage and still seeing the text from the Steps from PFD on top of the View port 2.0 for MaYa.
Please have a look into the video below.
yes, I’ve disabled PM-s because it’s always better when someone has an issue to write it down and ask for help in the forum sections. Because If some other people have that issue too they will ask for help or just subscribe for the post. Often people here help each other too.
So, did you open the link above containing all the useful information about how to get nightly builds?
