HI ,

when reading papers about visco-plastic or elasto-viscoplastic simulation, all authors only say that the orientation of grain used in the simulation can be randomly generated, and does not refer to how to generate them. I know the orientation of grain can be expressed by Euler angles (phi1, ph, phi2), but can someone give me advice how to generate euler angles?
