The solver is built on the deal.II finite element library, combining matrix-free operator evaluation, adaptive non-conforming meshes capabilities, and distributed-memory parallelism.\n  Two alternative treatments of the rotational and gravitational source","authors_text":"Allan Peter Engsig-Karup, Giuseppe Orlando, Letizia Bottani, Luca Bonaventura, Tommaso Benacchio","cross_cats":["cs.NA","physics.ao-ph"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"math.NA","submitted_at":"2026-05-28T08:36:56Z","title":"An IMEX-DG solver with non-conforming mesh refinement for atmospheric dynamics with rotation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.29598","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:17510acb2fb6c878721f0e1772d5e64d7c1b711d94519b628d9905515c302372","target":"record","created_at":"2026-05-29T01:05:50Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"cde0f62bb1240ac277b2cdd1fd0816d424ac3626e694af38e6f4082fece8d885","cross_cats_sorted":["cs.NA","physics.ao-ph"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"math.NA","submitted_at":"2026-05-28T08:36:56Z","title_canon_sha256":"8d57602c2a72dcbd45b2a7d483b84ff3463d0483ddf1589f4c4836f6c70b04ee"},"schema_version":"1.0","source":{"id":"2605.29598","kind":"arxiv","version":1}},"canonical_sha256":"14f2dbe96de9c6feb8368214b4f5afc659c18c5d4a36b785cf2e924684ee693d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"14f2dbe96de9c6feb8368214b4f5afc659c18c5d4a36b785cf2e924684ee693d","first_computed_at":"2026-05-29T01:05:50.025960Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-29T01:05:50.025960Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Zrpbj8GFUF5CUHTbaHs9iHHzN9zUus0daS2FiNXw+UyKzrI5fpeKRISPSQ4+buQ5BZpuQbbgkdhL1FnWWAWGDg==","signature_status":"signed_v1","signed_at":"2026-05-29T01:05:50.026555Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.29598","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:17510acb2fb6c878721f0e1772d5e64d7c1b711d94519b628d9905515c302372","sha256:527ae6cfc202e698e122f19c2c84fa147b460c6b0e75a83bf5df888c129b82cf"],"state_sha256":"accf3bbd58f361aed51fe2266e3642af3892822b7af0ec3fa7acc89b419a3ef6"}
