--- Comment #2 from JuzheZhong <juzhe.zhong at rivai dot ai> --- To build the attachment file, we need these following file from SPEC2017: module_big_step_utilities_em.mod module_cumulus_driver.mod module_fddagd_driver.mod module_model_constants.mod module_shallowcu_driver.mod module_comm_dm.mod module_dm.mod module_first_rk_step_part1.mod module_pbl_driver.mod module_state_description.mod module_configure.mod module_domain.mod module_force_scm.mod module_radiation_driver.mod module_surface_driver.mod module_convtrans_prep.mod module_em.mod module_fr_fire_driver_wrf.mod module_scalar_tables.mod module_utility.mod But I failed to create attachment for them since they are too big.
