The validation for the L2-QCGD simulation is based on the predictions of the MD simulations of a 50 nm grain sized 100 nm × 100 nm × 150 nm polycrystalline Al system as shown in (a). Similarly, the validation of the L4-QCGD simulations is based on the L2-QCGD simulations of a 100 nm grain sized 200 nm × 200 nm × 300 nm polycrystalline Al system as shown in (b), the validation of the L8-QCGD simulations is based on the L4-QCGD simulations using a 200 nm grain sized 400 nm × 400 nm × 600 nm polycrystalline Al system as shown in (c), and the validation of the L16-QCGD simulations is based on the L8-QCGD simulations for a 400 nm grain sized 800 nm × 800 nm × 1.2 µm polycrystalline Al system as shown in (d). A grain identity number is used to color the atoms to indicate that the orientation relationships and the numbers of grains are the same in all the microstructures.
