Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Well, for free you won't find much beyond a good google search.
However, if you check the Maya help, there are some tutorials in the fluids section.
Also, try the sample scenes in the Visor.
If you open the Visor sample fluid scenes, there are notes in the attribute editor for certain objects explaining in detail what each feature does.
So, check the help, there is a treasure trove of information there that others fail to notice
Good luck!

Fluids collision problem
Here's a specific problem. Why is it when I have a fluid colliding with an object, the fluid will eventually penetrate and show up on the other side of my collision object? I've looked through all of the settings, & I can't see a solution to the problem. What am I missing/
Thanks for the help.

1. Make sure your collision object is made of TRIANGLE polygons, not QUADS.
Triangulate the poly mesh explicitly using Polygons >Triangulate
2. Change the Tessellation Factor if necessary and click Apply and Close.
Maya internally converts NURBS objects to polygons before it animates the simulation. The Tessellation Factor sets the number of polygons created during the conversion. Lower numbers create coarser geometry and lessen animation accuracy (which means more fluid will appear to pass through the geometry), but increase the playback speed and processing time.
The default Tessellation Factor is 200. Try doubling the value as many times as necessary to get the desired smoothness. (Select the geometry and click the geoConnector tab in the Attribute Editor.)
Hope this helped!
Good luck!

Fluids Collision Problem
Thanks for the info. I tried what you suggested and it still didn't work. I had the tessellation factor over 5000 & still no luck. I used both polys converted to triangles & NURBS converted to triangles. The project I'm working on requires me to import a poly object (bottle) & I need to fill it from the bottom. If you have any more ideas, I'd really appreciate it.
Thanks!

Well, not to burst your bubble regarding Fluids, but despite its name, Fluids are currently better suited for gaseous effects than pouring water
So, to continue, I need to know what version of Maya you are running to determine what we can do to move forward with achieving what you want
If you are running Maya 2009, I already have a solution for you:
Duncan Brimsmead has a video tutorial for you using nParticles for pouring water into a glass here:
