What do we hope to learn from multi-D simulations?

• How does the ignition begin?

  • Convection is likely important in the moments leading up to the ignition — this is a 3-d problem.
  • How many locations does the burning begin at?

• Is the burning localized?

  • If so what localizes it?
  • How does it spread?
  • How fast does the burning spread?

• What are the effects of rotation?
