However, it is usually a non-trivial task to retain the flexibility and the accuracy simultaneously in the implementation of this approach. Based on the intrinsic nature of the LBM, we propose a simple and second-order accurate IB-LBM in this paper, where the no-slip boundary condition on the fluid-solid interface is directly imposed by iteratively correcting the distribution function near the boundary, markedly similar","authors_text":"Baiman Chen, Qing He, Shi Tao, Simin Huang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.comp-ph","submitted_at":"2018-03-26T01:27:49Z","title":"A distribution function correction-based immersed boundary- lattice Boltzmann method with truly second-order accuracy for fluid-solid flows"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.09380","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":"sha256:032ff1116c69f79dac8869656baed4b1650598652e91c4ad42ccc293b4a0537e","target":"record","created_at":"2026-05-18T00:20:01Z","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":"040f432301c598b10940268e4e6656b4c92ff22d5ee34e06ab0336a6ff8fa442","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.comp-ph","submitted_at":"2018-03-26T01:27:49Z","title_canon_sha256":"0efdb802b1d3b23bff54baafd5789c5429d754e4482233e0b46a04b39a7842b7"},"schema_version":"1.0","source":{"id":"1803.09380","kind":"arxiv","version":1}},"canonical_sha256":"d4f836aec59c0fed21078d641d9f4e85b964349388bf92776356a3c353728339","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d4f836aec59c0fed21078d641d9f4e85b964349388bf92776356a3c353728339","first_computed_at":"2026-05-18T00:20:01.226690Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:20:01.226690Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"RA9zV3GyuR/WFVvy2Xv9DGSLbro8QSTaujhkZLTqFvx7h0ba72Hf4FQNL/mePcz6rr8zV/3jTyW18nV/DcWRBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:20:01.227186Z","signed_message":"canonical_sha256_bytes"},"source_id":"1803.09380","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:032ff1116c69f79dac8869656baed4b1650598652e91c4ad42ccc293b4a0537e","sha256:e6fd4ea14848acf339b6f9d7793be51c8937851dc61b07588b07a6da2427198a"],"state_sha256":"b7dad551a25665ec00dc0cb6714f90fd2ea00663ae5be3721d0f7d55ad1f9ef2"}
