      "description": "Method used to compute van der Waals energy stored in energy_van_der_Waals_value. This metadata is used when more than one van der Waals method is applied in the same *single configuration calculation* (see section_single_configuration_calculation). The main van der Waals method (the one consistent with energy_current and used, e.g., for evaluating the forces for a relaxation or dynamics), is defined in settings_van_der_Waals.",
