"Error: Parent grain is not anisotropic"

Dear all,

In case you get the error

"Error: Parent grain is not anisotropic"

this is probably due to an inconsistent input in the "Data for further nucleation" section of the input file. When using "parent_relation" for definition of the orientation for the new seeds, an anisotropic parent grain is needed. Otherwise, the above error is displayed, and the simulation stops.
Therefore, in case of bulk nucleation, an anisotropic phase should be chosen for the reference phase. In case of "interface", "triple" or "quadruple", the substrate phase will be used for determining the parent grain and thus should be anisotropic.
