I have continued on with my latest blog post: http://elliotfourvfxartist.blogspot.com/2015/01/gas-fire.html
I have increase the resolution but also touch up a few things inside the fluid parameters. For instance I add more color swatches for the incandescence as well as the smoke color. I have also written some expressions to give the fire a small twist in its X and Y origin. A few touch up can really make or break your effect you’re trying to recreate.
