Description: Check whether a model is invariant with respect to rigid-body
motion (translation and rotation) as required by objectivity
(material frame-indifference). This is expected to be true for any
model that does not depend on an external field. The check is
performed for a randomly distorted non-periodic body-centered cubic
(BCC) cube base structure. Separate configurations are tested for
each species supported by the model, as well as one containing a
random distribution of all species. The energy and forces of each
configuration is compared with that of the same configuration
rotated about a random axis by an irrational angle and translated
in a random direction by an irrational distance. The verification
check will pass if the energy of all configurations that the model
is able to compute are invariant and the forces are mapped back by
the inverse rotation. Configurations used for testing are provided
as auxiliary files.
