What are the possible reasons to get the error " Thermo-Calc error 1611 MICRESS error 22 phases 1/ 1"

phase 1 is FCC_L12

Hi Chamara,

error 22 indicates that the single-phase equilibrium which is calculated for extracting diffusion coefficients was not successful. This e.g. can be the case if the average phase composition is inside a miscibility gap. Using "diff_comp sets" may help in such a case, because then the other composition sets are allowed to take part in the equilibrium, and only the composition of the correct set is used for calculation of the diffusion coefficients.
However, I also had the case where "diff_comp sets" produced the error, because the compositions of the other composition (which any way was not stable) set could not be calculated correctly...
