With Identify Grains, individual grains are identified and analyzed in a given structure. The method introduces a segmentation of the grains, based on a distance transformation, which identifies the number of grains, as well as the grain volume, sphericity, and the orientation of the grains. Based on the statistical properties of the identified grains, a digital twin of the structure can be created with GrainGeo. Find more details about the theory behind Identify Grains in the Theoretical Background section.

To successfully identify grains, the parameters for the command must be chosen carefully. The built-in default values cannot be set to deliver the best possible results for all applications. Best practice is to carry out a parameter study for the solver parameters at the beginning of the analysis.
