====== Potential models ======
----

//potfit// supports different ways of defining atomic interactions. All of them use a set of parameters $\alpha_i$ to define a potential function. Depending on the particular implementation these parameters have very different meanings.

Currently //potfit// supports the following models:
  * [[analytic|Analytic potential functions]]
  * [[openkim|KIM interactions]]
  * [[tabulated|Tabulated potential functions]]
