The coupling approach generalizes prior coupling methods using a cell-based decision. The approach is supported by a lifting and restricting operator, which translate length and time scales between DSMC and MD. We verify the framework on basic conservation laws, and demonstrate its usability on a hypersonic flow example. Its accuracy gain is discussed in light of conventional DSMC simulations. Advantages and limitations are discussed, and additional use cases are highlighted.","authors_text":"Dane Sterbentz, Jean-Pierre Delplanque, Jonathan Belof, Niels Gr{\\o}nbech-Jensen, Tim Linke","cross_cats":["cond-mat.mes-hall","cond-mat.stat-mech"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.comp-ph","submitted_at":"2025-06-02T17:43:58Z","title":"A Concurrent Multiscale Framework Coupling Direct Simulation Monte Carlo and Molecular Dynamics"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2506.01924","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:c664fd9d85bf926ce4b6d73662258a5228bd8a171695f09c264c9b660b7b0787","target":"record","created_at":"2026-07-05T11:14:21Z","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":"e42f742ec21f5fbb8baef88cbc3ce42ead352351d7eabe9b5ad05d41e0cbacac","cross_cats_sorted":["cond-mat.mes-hall","cond-mat.stat-mech"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.comp-ph","submitted_at":"2025-06-02T17:43:58Z","title_canon_sha256":"076d76442de209cafa1517e071da1a631883fbd54e3c722d209660932e879a65"},"schema_version":"1.0","source":{"id":"2506.01924","kind":"arxiv","version":1}},"canonical_sha256":"84b9409b32fd8e8b97d1e62d0f784e1ec7c50e9295bf535a6d6f56122f6e65a7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"84b9409b32fd8e8b97d1e62d0f784e1ec7c50e9295bf535a6d6f56122f6e65a7","first_computed_at":"2026-07-05T11:14:21.492916Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:14:21.492916Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"2LkTkL3IPTkWQIF5TdV66ApCjqatfvl1B3eD/dbKAQf50NFCDC3kitIJwB1nZazqQAXa4m6DxrU77b4P529GAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T11:14:21.493384Z","signed_message":"canonical_sha256_bytes"},"source_id":"2506.01924","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c664fd9d85bf926ce4b6d73662258a5228bd8a171695f09c264c9b660b7b0787","sha256:8c06ce9cc1be633f876acee3a018d6008dd711ad9ffcd2d15e9f1ed90304577e"],"state_sha256":"e52779661c87e004e2eba219951867f51a05328084e10f875cb21176f1260c4e"}
