PhoenixFD medium explosion in 4K

An explosion I made with Chaosgroup PhoenixFD. Using massive scale vorticity and slowed down 4 times. Rendered with vray 3 at 4k.

754 million cels. 2 to 3 min/frame fora main sim and then 4 to 5 min/f for a 4x slow down. Direct symmetric, multi-pass, massive scale vorticity.
