This method can be used to strongly enforce continuity of spatial derivatives as well as solution value over element boundaries, which is necessary for solving fourth order partial differential equations (PDEs) in primal form and useful for some second order PDEs. The implementation is verified by solving the wave equation based on a modification of the PDE with a Lax\u2013Wendroff-like procedure, allowing a high-order solution method with negligible additional computing time.\n                  <\/jats:p>","DOI":"10.1145\/3797876","type":"journal-article","created":{"date-parts":[[2026,2,16]],"date-time":"2026-02-16T15:00:03Z","timestamp":1771254003000},"page":"1-31","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["A Novel Implementation of Hermite Finite Element Methods in the deal.II Library"],"prefix":"10.1145","volume":"52","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1396-2287","authenticated-orcid":false,"given":"Ivy","family":"Weber","sequence":"first","affiliation":[{"name":"Department of Information Technology, Uppsala University, Uppsala, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8406-835X","authenticated-orcid":false,"given":"Martin","family":"Kronbichler","sequence":"additional","affiliation":[{"name":"Faculty of Mathematics, Ruhr University Bochum, Bochum, Germany and Department of Information Technology, Uppsala University, Uppsala, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8865-8218","authenticated-orcid":false,"given":"Gunilla","family":"Kreiss","sequence":"additional","affiliation":[{"name":"Department of Information Technology, Uppsala University, Uppsala, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2026,4,8]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1515\/jnma-2024-0137"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1137\/11082539x"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cma.2019.03.020"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcp.2024.113597"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.camwa.2020.06.009"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1137\/18m1171072"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.camwa.2020.02.022"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1515\/cmam-2020-0159"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1145\/2049673.2049678"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1145\/1268776.1268779"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00607-008-0003-x"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00211-010-0338-z"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1137\/24m1653689"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-36519-5"},{"key":"e_1_3_2_16_2","first-page":"397","volume-title":"Proceedings of the Conference on Matrix Methods in Structural Mechanics","author":"Bogner F.
