I am in this same boat. I am trying to simulate this explosion effect:
After many days of trial and error, I've gotten this effect thus far, but I had to result to using a poor quality video for my fire and smoke:
However, there is only one tutorial out there when it pertains to X-Particles Explosia, Octane, etc., but that video does not discuss creating artificial containers for the explosions, simulating exhaust, etc. So much confusion on this feature in X-Particles and there is hardly any resources out there to learn, plus the community is pretty small which makes it even harder to learn. I'd be willing to pay someone for the time but even that I'm finding difficulty!
Here's a simple file that strips all the internal modeling. If anyone from Insydium, the community would be willing to help, shoot me a reply here, my email Smith.Brandon@basco.com, or feel free to DM for my phone number as I'd like to move along on my project sooner than later:
Sorry if this technically hijacked the thread, but for a forum with only 10 total topics and one of them pertaining to the same issue I was having I figured it was OK to post here.
