Welcome to Valhalla, your source for Bifrost-related tutorials, techniques, tricks, hacks and ideas!
I'll be posting Bifrost-related information at a variety of levels, from simple how-to's for the generalist, to in-depth, technical explanations for the advanced TD.
Bifrost FX is still relatively new, but there is a growing source of information available. If you're new to Bifrost, here are some good places to start:
Maya 2016 Documentation
Of course, the Maya 2016 documentation is the place to be if you're just starting out. This page in particular will help you get started if you've never used Bifrost before.
The Area Forum
The Dynamics forum on The Area is attended by quite a few Autodesk designers, developers and QA people, as well as people who have been using Bifrost since Maya 2015.
Igor Žanić's Work
Igor has been working on some production-level Bifrost tests and simulations, and he's on his way to building a library of Bifrost effects. His R&D is invaluable to understanding how things work at the generalist level. Two pages that are helpful are Igor's Bifrost 2016 page and Igor's channel on Vimeo.
Daryl Obert has covered Bifrost usage from a high-level demo perspective on his Youtube channel. In particular, Guided Simulations in Bifrost and Adaptive Aero Solver in Bifrost will give you a basic idea of what to expect in setting up a scene.
I did up a little aero demo for the inaugural video. It shows how to do emission for a simple aero explosion.
