Dear Vasilis,

Yes,you are right.I am not having any region assigned to Deuteron or Triton and the mixture is not given in volume fraction.
The density value is unimportant.So,according to your idea,I can leave the density value of Deuteron and Triton blank. Right?

You think,for ideal gases we can always calculate the density from the PV=nRT law knowing the pressure.But,In this problem,
Deuteron and Triton are solid state,not gas state.So,I have a doubt for the density value of Deuteron and Triton in the input file
you give me.

Yours,
Chenyuan
