At the heart of the code - the new original low-dissipation numerical method based on a combination of operator splitting approach and piecewise-parabolic method on the local stencil. The details of the numerical method are described; the main tests and the scheme of parallel implementation are shown. The chemodynamics of the hydrogen while the turbulent formation of molecular clouds is modeled.","authors_text":"Igor Chernykh, Igor Kulikov, Viktor Protasov","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2016-08-31T07:11:43Z","title":"A New Code for Numerical Simulation of MHD Astrophysical Flows With Chemistry"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1608.08748","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:de335d2958814c2562b08b928921f4b1e4c70859e05bf67778a23ca8f2f8325c","target":"record","created_at":"2026-05-18T01:06:40Z","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":"7e2aa4081a099c9bd93ee233270b0f1f8aba650fb217fa586eb3496d6b844736","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2016-08-31T07:11:43Z","title_canon_sha256":"57d206e25b44af62cad0de33a75cc4318e796c26c2d490474b6a624c7307d8d3"},"schema_version":"1.0","source":{"id":"1608.08748","kind":"arxiv","version":1}},"canonical_sha256":"190b8a0136a6e67ac222206e6240688c52c5ddf157ff61e8aeeffed416b51a64","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"190b8a0136a6e67ac222206e6240688c52c5ddf157ff61e8aeeffed416b51a64","first_computed_at":"2026-05-18T01:06:40.004869Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:06:40.004869Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"OfbyozucsXkRTCa3UaOukGbqBAp297oix8Dpbap4sIvqAjfwweR4YXx4Upg1IvE55RaxwsGkDNmeenGiuCjJAw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:06:40.005479Z","signed_message":"canonical_sha256_bytes"},"source_id":"1608.08748","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:de335d2958814c2562b08b928921f4b1e4c70859e05bf67778a23ca8f2f8325c","sha256:f863f914584ac78e66d0038eef547efb7651b4db07468c06125b2f83abd03f6a"],"state_sha256":"28d0911041150a166e5b8358944d91cbbe4de459afb311bd125cf71dd675cfff"}
