I've to say that the more that I dig in realflow the more it looks cool. For one of my workshop I was trying to simulate the spilling of the blood in a wound like this http://www.slate.com/articles/video/vid ... video.html
(even if I found quite un-natural the spilling I want to check this).
It seems that I need to simulate some kind of "sponge" effect of the muscle, but I didn't have luck since now.
If you are interested I can share the scene and all the info I've gathered since now.
