Crystal orientation definition for statistically equivalent RVE

[gomezbenavente]

Hi,

I have a dataset of grain orientations (specifically, using the Euler angles description), from which I can obtain a 3-variate normal distribution that is representative of that dataset. If I want to generate a statistically equivalent RVE in terms of orientations, is there a way to introduce the parameters of my distribution into Neper as an orientation distribution function (ODF) so that they are taken into account when generating the RVE?

I have tried using the -ori command, but I can't understand why I have to indicate as well a "discrete orientation" in addition to the ODF, because the Euler angles on the dataset are defined w.r.t. the global frame of reference.

Thank you in advance.
Kind regards,

In -ori, the 3-variate normal distribution is defined about a nominal orientation, as in Goss:"normal(theta=...)".
