Dear OPENKIM users:
I would like to learn how to calculate the total force and total energy of a free carbon cluster( without substrate) with a second generation Brenner potential( model_ArCHHeXe_BOP_AIREBO__MO_154399806462_000). If possible, can you show me how to modify the existing example, say ex_test_Ar_free_cluster_CLUSTER_F90 and replace the “Ar” with carbon and also change potential to Brenner. If elsewhere has instruction to my question already, would you please show me where is the documents or place so i can learn it. Many thanks.
