To run a simulation all that is necessary is to first build a model crystal (created using the Diffusion Domain parameters window) and a temperature-time (T-t) path created using the Age Plot and P-T-t Path window.   Then run a simulation using the button provided.   

N.B. the toolbox and the instructions menu items  outline specific options, in order that specific tasks might be undertaken.
