ElastoDict can handle non-isotropic constituent materials. For these materials, an orientation has to be additionally specified. If the analyzed structure consists of analytical objects (gad data), the orientation of these objects is used when Use Orientation from Analytic Objects (gad) is selected.

Alternatively, with Load Orientation Information from File (*.gof), orientation information can be loaded from a file. Such a file can be generated for example with GrainFind for granular structures. The third option, Use the Global XYZ-Coordinate System, allows to use anisotropic materials even if no orientation information for the structure is available.
