Our goal is to enable future research on the capabilities and potential advantages of discontinuous Galerkin methods for complex multiphysics simulations in astrophysical settings. We give specific details and adjustments of our implementation within the flash framework and present extensive validations and test cases, specifically its interaction with several other physics modules such as (self-)gravity and radiative transfer. We conclude that the new DG solver module in flash is ready for use in astrophysics simulations and thus ready for assessments and investigations.</jats:p>","journal":"Monthly Notices of the Royal Astronomical Society","year":2022,"id":23842,"datarank":0.30279366276614805,"base_score":1.6094379124341003,"endowment":1.6094379124341003,"self_citation_contribution":0.24141568686511508,"citation_network_contribution":0.061377975901032986,"self_endowment_contribution":0.24141568686511508,"citer_contribution":0.061377975901032986,"corpus_percentile":null,"corpus_rank":null,"citation_count":4,"citer_count":4,"citers_with_citation_signal":3,"citers_with_endowment":3,"datacite_reuse_total":1,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":144939,"name":"Stefanie Walch","orcid":null,"position":1,"is_corresponding":false},{"id":144940,"name":"Gregor Gassner","orcid":null,"position":2,"is_corresponding":false},{"id":144938,"name":"Johannes Markert","orcid":"0000-0001-6297-9494","position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":1.6094379124341003,"endowment":1.6094379124341003,"datacite_reuse_total":1,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"18998881","pmcid":null,"openalex_id":"https://openalex.org/W4210533985","authors":[],"funders":[{"funder_name":"European Research Council","grant_id":"679852","title":"The radiative interstellar medium"},{"funder_name":"Deutsche Forschungsgemeinschaft","grant_id":"184018867/SFB 956","title":"Conditions and Impact of Star Formation - Astrophysics, Instrumentation and Laboratory Research"}],"total_grants":2,"fwci":0.6638,"citation_percentile":0.59605523,"influential_citations":0,"citation_trend":[{"year":2022,"count":1},{"year":2023,"count":2},{"year":2025,"count":1}],"oa_status":"green","license":"OUP Standard Publication Reuse","oa_locations":[{"url":"https://arxiv.org/pdf/2112.11318","host_type":"repository"},{"url":"https://arxiv.org/pdf/2112.11318","host_type":"GREEN"},{"url":"https://arxiv.org/pdf/2112.11318","host_type":"repository"},{"url":"https://academic.oup.com/mnras/advance-article-pdf/doi/10.1093/mnras/stac298/42378655/stac298.pdf","host_type":"publisher"},{"url":"https://academic.oup.com/mnras/article-pdf/511/3/4179/42594426/stac298.pdf","host_type":"publisher"},{"url":"http://arxiv.org/abs/2112.11318","host_type":"repository"},{"url":"https://doi.org/10.1093/mnras/stac298","host_type":"journal"},{"url":"http://arxiv.org/pdf/2112.11318","host_type":""},{"url":"https://dx.doi.org/10.48550/arxiv.2112.11318","host_type":""},{"url":"https://arxiv.org/abs/2112.11318","host_type":""}],"fields_of_study":["Computational Fluid Dynamics and Aerodynamics","Combustion and Detonation Processes","Gas Dynamics and Kinetic Theory","Physics"],"mesh_terms":[],"keywords":["Physics","Multiphysics","Solver","Discontinuous Galerkin method","Flash (photography)","Computational science","Finite element method","Thermodynamics","Programming language","Computer science","Optics","FOS: Mathematics","FOS: Physical sciences","Mathematics - Numerical Analysis","Numerical Analysis (math.NA)","Astrophysics - Instrumentation and Methods for Astrophysics","Instrumentation and Methods for Astrophysics (astro-ph.IM)"],"sdg_mappings":[],"linked_datasets":[{"doi":"10.48550/arxiv.2112.11318","title":"A Discontinuous Galerkin Solver in the FLASH Multi-Physics Framework","publisher":"arXiv","resource_type":"Text"}],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-06-07T20:42:23.736685Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
