=============================
What can you do with SPPARKS?
=============================

This tutorial has a focus on *grain growth* type applications but *spparks* can
do a lot more than that.

* Sintering in a `nuclear fuel`_ (Veena Tikare)
* Many more (see `Pictures and Movies`_) on *spparks* website
* Model grain growth and evolution (*this tutorial*)

Motivations
-----------
* Strength, toughness and crack growth resistance are intimately tied to
  microstructure
* Significant effort goes into control of microstructure
* Predictive tools such as *SPPARKS* have *potential* to enhance understanding
  of heat treatment processes and perhaps shorten development time of new
  processes
