While efficient solvers have been proposed for fast simulations, methods that are both real-time and accurate are still an open challenge. An ideal, interactive solver would be able to provide physically and numerically accurate results at high frame rate, which requires efficient force computation and time integration. Towards this goal, we explore in this paper for the first time the use of neural networks to directly learn ","authors_text":"Ahmet Tuysuzoglu, Andreas Maier, Felix Meister, Tiziano Passerini, Tommaso Mansi, Viorel Mihalef","cross_cats":["physics.med-ph","q-bio.TO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"q-bio.QM","submitted_at":"2018-12-13T18:57:53Z","title":"Towards Fast Biomechanical Modeling of Soft Tissue Using Neural Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1812.06186","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":"sha256:16a2f7d2e806c7b8ac75dd263555823f7bc590ae909a511f2d0f85ed97ecc117","target":"record","created_at":"2026-05-17T23:58:12Z","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":"5a5fd8c471ab0d8e2f0cfc05f163273bb9bdcdda073f6625e0f4e410cf360cb6","cross_cats_sorted":["physics.med-ph","q-bio.TO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"q-bio.QM","submitted_at":"2018-12-13T18:57:53Z","title_canon_sha256":"8858292e1cee3f9f60d9f4c8bbb9d139fc0330c4b3f70cb87a5342c00a16429e"},"schema_version":"1.0","source":{"id":"1812.06186","kind":"arxiv","version":1}},"canonical_sha256":"14aa72419adb2e50ea48cf13d217166a650785bf42a86808d50dac135feaec18","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"14aa72419adb2e50ea48cf13d217166a650785bf42a86808d50dac135feaec18","first_computed_at":"2026-05-17T23:58:12.927704Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:58:12.927704Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"PaW9JOrRwV/k9KcLxJgDB2VgWnk6+tnYs6/+tHKzmsFYdt8FU8dsHYMHzSKV9eVPBBVCJUKWu15ZMRO1VcVcBg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:58:12.928202Z","signed_message":"canonical_sha256_bytes"},"source_id":"1812.06186","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:16a2f7d2e806c7b8ac75dd263555823f7bc590ae909a511f2d0f85ed97ecc117","sha256:25d84b0817553c960faa4c7e8a4f9b107b8a39dd7760a44c4ef9f79f93ccf868"],"state_sha256":"6a32775b66b632a38c14dc43f5da16e077de958e087750b78b382263a83a16de"}
