Is there a realistic fluid simulator for Max?
show user profile  bratok_new
Hi guys,
I've been away from Maxing for a while, so I might be not up to date on all the latest plugins...
I know there are lots of fluid simulators out there, but I wanted to ask, if this simulators are also mathematically / physically accurate?

Let's image we have a cylinder like this, filled with 8760 mm3 of liquid, with a nozzle on one end and a plunger on the other.
An explosive charge goes off behind the plunger, releasing 45 joules of energy, and pushing the liquid out of the nozzle.


And I need to accurately simulate how the liquid will fly out of the nozzle... do you think Max is a good place to start with this would I be better with some other approach?

Thanks! ;)

I would look into "Pro E"

I think they have some fluid dynamic support for that software, but everything is super expensive, but it would be more accurate than 3ds I'd say.

No. Max would be pretty much the worst place to start.

There is scientific simulation software that is made to do precisely this sort of thing. I can't remember any names, but there is even an open source fluid solver. No idea how you'd get that data into max though.

afaik they are all brute force and iterative so while you can get realistic results if you turn the specs high enough, they will never be accurate nor time efficient

if you don't require a max based solution.

Question: So does it need to "look accurate" or BE accurate?

And I only ask this because why would physical accuracy (to 100% as opposed to say 90%) matter? If its a visual presentation ?

someone's taking their supersoakers way too seriously btw.

OpenFoam is used for this sort of thing.

It's kida of an advanced supersoaker...


but guess you're right, it probably would be easier to test it in reality and see how it works, instead of trying to get hand onto serious scientific simulation software...

You know those sower heads that can change the type of nozzle and stream size by turning?
That's your solution

Nobody has mentioned realflow yet.

I have had mixed success with realflow, it is extremely resource hungry. If you want realistic, you will need some decent processing power and memory.

^ yup, I had one rF scene that ate up 180 gigs of memory : / looked great tho

Try Phoenix, its chaos software and its voxel based :D (all in max viewport too)




Doesnt take very long to learn either- give it a couple of hours with a few youtube tutes youl be on your way

Phoenix looks much simpler than realflow. How does it compare for resource usage?
