dIFFUSION OF Au and Sn

Please login with a confirmed email address before reporting spam

Hi All,
I have to model the diffusion behavior of Au and Sn into each other. Attached is the file where I modelled the Diffusion of Au into Sn and then Sn into Au but individually. In reallity this must happen in both direction that is when Gold is diffusing into Tin ,at the same time, Tin must also diffuse into Gold but with little less speed.
My question is that how I can couple these two physics to get one single mode that work for both diffusing species simultaniously?.

Thanks a lot

Warm regards
Saqib Rafique
