app_style potts/strain/pin Q
app_style potts/strain/pin 100
This is an on-lattice application which evolves a Q-state Potts model with a per-site strain, where each lattice site has a spin value from 1 to Q. The application also allows for pinning of sites using a special spin value of Q+1. Sites flip their spin as the model evolves but sites are not allowed to flip to a pinned value; sites with pinned values also do not flip. Strain energy can influence grain growth.
See the app_style potts_strain and pin commands for details on how strain and pinned sites are incorporated into this application.
The following additional commands are defined by this application:
app_style potts, app_style potts_strain, pin
