The paper provides a comparative analysis of existing FEM approaches, exploring the strengths and challenges of various modeling choices in the literature. Additionally, we introduce a sample framework for developing FEM models of SCG, detailing key methodologies from governing equations and meshing techniques to boundary conditions and material property selection. This framework serves as a guide for researchers aiming to create accurate models of SCG signal propagation and offers insights into capturing complex cardiac mechanics and their transmission to the chest surface. By consolidating the current methodologies, this paper aims to establish a reference point for advancing FEM\u2010based SCG modeling, ultimately improving our understanding of SCG waveforms and enhancing their reliability and applicability in cardiovascular health assessment.<\/jats:p>","DOI":"10.1002\/cnm.70047","type":"journal-article","created":{"date-parts":[[2025,5,19]],"date-time":"2025-05-19T13:50:09Z","timestamp":1747662609000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Computational Modeling of Cardiovascular\u2010Induced Chest Vibrations: A Review and Practical Guide for Seismocardiography Simulation"],"prefix":"10.1002","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3900-6704","authenticated-orcid":false,"given":"Mohammadali","family":"Monfared","sequence":"first","affiliation":[{"name":"Department of Bioengineering Lehigh University  Bethlehem Pennsylvania USA"},{"name":"Biomedical Engineering Program, Mississippi State University Mississippi State  Mississippi USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peshala T.","family":"Gamage","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering and Science Florida Institute of Technology  Melbourne Florida USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6900-7129","authenticated-orcid":false,"given":"Ali","family":"Loghmani","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Isfahan University of Technology  Esfahan Isfahan Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5962-186X","authenticated-orcid":false,"given":"Amirtah\u00e0","family":"Taebi","sequence":"additional","affiliation":[{"name":"Department of Bioengineering Lehigh University  Bethlehem Pennsylvania USA"},{"name":"Biomedical Engineering Program, Mississippi State University Mississippi State  Mississippi USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,5,19]]},"reference":[{"key":"e_1_2_16_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2022.05.033"},{"key":"e_1_2_16_3_1","doi-asserted-by":"publisher","DOI":"10.3389\/fphys.2019.01057"},{"key":"e_1_2_16_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-023-38607-7"},{"key":"e_1_2_16_5_1","doi-asserted-by":"crossref","unstructured":"M.
