Clear/Delete Simulation?

[jayroth]

In my various attempts at getting XP to work with FumeFX, I have the XP emitter set to create Thinking Particles (which fails). I also have a validation test, using Thinking Particles and Particle Geometry, which works as expected. Unfortunately, I cannot seem to disable or delete the cache or sim that was created from the validation test, and so far, I cannot see an entry in the docs or the UI that allows me to do so.

What steps should I take?
