Hey guys,
Since I have seen on some of the LW comments that a lot of people have expressed a desire for a Liquid simulation engine within LW,
I have decided to help out a bit.
I will be posting on this thread papers/videos/ libraries link that could help developers create a cool liquid sim engine for LW.

So if you are a 3rd party dev, look into the papers I will be posting on this thread. Or help me us out posting ideas, libraries/ links.

Here is what I what I have found so far:

A Stream Function Solver for Liquid Simulations
Ryoichi Ando, Nils Thuerey, Chris Wojtan
Paper/Video http://pub.ist.ac.at/group_wojtan/projects/2015_Ando_ASFSfLS/index.html



and a whole bunch of links here:

Great, I am very inexperienced in writing codes but I have knowledge on Mathematics and Physics of waves and fluids. Do you think it can be helpful? I would like to participate in these kind of technical discussions.

It might, for people who can code, understand the current LW SDK and are motivated to try.
Hell we need people like you that can explain the math to interested coders.

Here are some more cool papers from SIGGRAPH 2015:

Personally I don't know why people are so keen on getting a fluid Simulator in LightWave when there are so many fundamentals in LightWave that need fixed. Besides, we already have ways of getting fluids in LightWave through Real Flow or even free in Blender.

I can't agree more. There is so much to do before that.
It would be smarter to make more robust support for RF or Blender fluids/particles data.

Edit : That said, thanks for the very interesting links :)

Well I am hoping to at least encourage a third party dev to pick up the ball..
Anyway here is another paper from 2009

I remember that Creacon was cooking something with fluids...don't know if it is still current.

This is my opinion that if LW can afford sth unique in this area then why not? Maybe developers can make sth that realflow or blender either don't have or are very difficult and flawed.

I have always been a dabbler in writing codes but am definitely ready to cooperate here. I am definitely confident of my math/physics background also and am willing to sleep one hour less and explore different aspects of this area but I don't know how to start.

I am sure that pure Physics/Math will not be required that much and numerical calculation of equation that Mr Roberto Ortiz showed will be needed.

What will you say?
