Explosion spreading rather than rising

[duke2]

I maxed out fuel and smoke buoyancy (10.0) but my explosion is still spreading rather than rising. I'll post a video in a moment.

What kind of geometry do you use? You can add a discharge modifier to Source's discharge and make the emission only on the top side of geometry (Normal Z mode). In this way, the spreading should be reduced.

Also, note that rising up mostly depends on the temperature and gravity, as well as on the simulator scene scale.

And one more thing - if you have a strong discharge near a solid obstacle, it's normal for the explosion to flatten out.

I replaced it with a disc and now it bangs off to the side

Too small disc for that resolution. Increase the grid's resolution or size of the disc.

Larger disc, finer grid resolution fixed it. Now how do I get rid of the lingering orange and turn it into smoke?

Experiment with the render settings The GPU preview could help you iterate more quickly.

Cheers!
