Our scheme relies on a segregated treatment of the subproblems, in particular on an explicit Robin-Neumann algorithm for the fluid-structure interaction, aiming at reducing the computational burden of numerical simulations. The results, both in an ideal and a realistic cardiac setting, show that the proposed scheme is stable at the regimes typi","authors_text":"Alfio Quarteroni, Christian Vergara, Giacomo Gigante, Martin Geraint Gabriel, Michele Bucelli","cross_cats":["cs.NA"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"math.NA","submitted_at":"2022-10-03T13:24:44Z","title":"A stable loosely-coupled scheme for cardiac electro-fluid-structure interaction"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2210.00917","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":"sha256:5f3bff545fe015a5c013730cb2addc89131d0801e48a08e5f9896611206b1f71","target":"record","created_at":"2026-07-05T06:38:28Z","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":"583a228e6aabe8da3dbe8dab579905de8c127816a114b7e4d3624dcd08a1fe53","cross_cats_sorted":["cs.NA"],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"math.NA","submitted_at":"2022-10-03T13:24:44Z","title_canon_sha256":"0b89ea540ac4fb2e47b00153a6f1b2870bfc1bb5ad161adac3233d9bdf11e615"},"schema_version":"1.0","source":{"id":"2210.00917","kind":"arxiv","version":1}},"canonical_sha256":"f9a8221363d393b96fae7302fc4a138207c1aafccf84d212067e45c62b16e6df","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f9a8221363d393b96fae7302fc4a138207c1aafccf84d212067e45c62b16e6df","first_computed_at":"2026-07-05T06:38:28.666216Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:38:28.666216Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ztpZglAyiemahVnYu7z3wOAjOQ1wvPgrxAYaWR9dmvH0IDro8/pZWarkf+ds5Lyj/esEG9K+ui7KvwspjCB6Dg==","signature_status":"signed_v1","signed_at":"2026-07-05T06:38:28.666757Z","signed_message":"canonical_sha256_bytes"},"source_id":"2210.00917","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5f3bff545fe015a5c013730cb2addc89131d0801e48a08e5f9896611206b1f71","sha256:ae47a2c98d1377f08915cf472c915ecb78bc6285e2a7227e1c7318d850a2741a"],"state_sha256":"53433a9c293c7312b7c9b822e97dd710c93f8a78ee76264b22fde7b01cd03172"}
