Hello! I am trying to use calphy v2.0.1 to calculate the free energy of an HCP crystal with two lattice constants. The documentation says that in the calculations section of the input file, the lattice_constant field can be assigned either a float or list of floats:
However, when I assign a list of two floats:
- element: Ti
lattice: hcp
lattice_constant: [2.95, 4.68]
mass: 47.867
I get this error:
