You can use only the following natural forces with explosion simulations: eddy, fan, gravity, and wind.
You can use the Explosion simulator to effectively reproduce various kinds of explosions and a whole range of related particle phenomena such as smoke, dust, gases, flames, and sparks.
Explosion simulation uses its own particle operator (ExplosionOp operator) and emitters: only the default sphere or cylinder emitter objects can be used with it—not any other object in XSI.
As with real explosions, there are different elements or “structures” found in simulated explosions. It is from the interaction and dynamics of these structures that an explosion takes shape.
Like other particle simulations, you can have the explosion particles collide with obstacles or be influenced by natural forces. There are two different approaches to managing obstacle collisions: collisions with structures only, or collisions with structures and particles. The computation time is directly proportional to the collision precision settings.
For more information on these, see Collisions with Obstacles and Natural Forces.
