Finally I finished my project. I like the result but I can improve it (fire detail for example).

I changed a lot of parameters, but I think the key is to change the frame rate, from 24 to 72, to get more realistic velocity.

So I just ran across this on Vimeo. This is about as good a setup I ever seen.

 

 

Before this one, the setup used done for the Russian film "Ispytanie" ("The Test") was my personal Houdini-nuke favourite...

 

 

Oh, and on a sidenote, "Ispytanie" is pretty cool as it's a 1 hour, 46 minute movie, but has no dialogue at all. But it's at least has a big boom. :D

The second video is insane, but the simulation data is about 9 Terabytes!! Mine is about 80 Gygabites.... and he have 48 gb of RAM, I have 16...

Anyway I'm happy with my results at the moment, I learnt a lot. In the future I will have a best pc and more storage

In the " test "you can see that nuclear blast were done in parts. And not as one whole explosion.

I'm in no way critiquing any work shown in this thread, I just wanted to share what I believe is the best CG reference out there. :)

As you should, imo, at least for the main explosion and the ground effects. Setting it up as one sim will force you into tweaking hell, as well as being less controllable, in production you would never do a setup like this as one simulation, it would be a disaster.

I know, no problem, but it's a bit depressing to know that the way to make a good explosion is with 9 Tb of data. I  thought that 80 gb was enough to do a homework explosion... and this doesn't even reach 1%  :o

There is absolutely no need to do that high res simulations for good results and I'm pretty certain those 9 TB is the total disk space used including RnD and tests, not just for the final sim...
