摘要: We present ROBO, a model and its companion code for the study of interstellar medium (ISM). The aim is to provide an accurate description physical evolution ISM set ground ancillary tool be inserted in NBody-Tree-SPH (NB-TSPH) simulations large scale structures cosmological context or formation individual galaxies. consists gas dust. chemical composition regulated by network reactions that includes number species (hydrogen deuterium based molecules, helium, metals). New reaction rates charge transfer H + H2 collisions are presented. dust contains standard mixture carbonaceous grains (graphite PAHs) silicates which follows destruction several processes. takes into account treatment cooling process, on mechanisms, functions recently reported literature. applied wide range input parameters results important quantities describing state organized database suited artificial neural networks (ANNs). Once trained, ANNs yield same obtained with great accuracy. plan develop suitably tailored applications NB-TSPH and/or
