In the lammps,i choose the fix atc commond an my tool to simulate the molecular dynamics-two temperature model , I want to do the Heat transport analysis for femtosecond laser ablation with molecular dynamics-two temperature model method .However,I can not figure out the material parameter about the " ttm.mat "file ,the material I used is the alloy of CrNiFe.Here exists two questions below:
1.the example of Cu_ttm.mat doesnot equal the alloy,and i cannot find the fomat and example of alloy,can you share one example of alloy for me and explain it to me ?
2. if the material parameters in .mat file between the commond of fix ttm and fix atc are the same or different?
Looking forward to your return,
