Warning: This is an example potential. Please do NOT use it for any real simulations!
This is an EAM potential that can be used in potfit.
It makes use of the global parameters and smooth cutoff features.

The pair and transfer functions (morse_sc and csw2_sc) use the smooth cutoff feature. The cutoff
parameter h is shared by using a global parameter.
The example potential can be generated with the following makeapot command:
makeapot -n 2 -i eam -g -f 3*morse_sc 2*csw2_sc 2*bjs
