The FE2TI approach is used in the project &amp;ldquo;EXASTEEL &amp;ndash; Bridging Scales for Multiphase Steels&amp;rdquo; (within the German priority program &amp;ldquo;Software for Exascale Computing &amp;ndash; SPPEXA&amp;rdquo;) for the simulation of modern dual-phase steels. This approach incorporates phenomena on the microscale into the macroscopic problem by solving many independent microscopic problems on representative volume elements (RVEs). The results on the RVEs replace a phenomenological material law on the macroscale. In order to bring large micro-macro simulations to modern supercomputers, in the FE2TI approach a highly scalable implementation of the inexact reduced FETI-DP (Finite Element Tearing and Interconnecting &amp;ndash; Dual Primal) domain decomposition method (scalable up to 786432 Mira BlueGene\/Q cores) is used as a solver on the RVEs. Weak scalability results for the FE2TI method are presented, filling the complete JUQUEEN at JSC J&amp;uuml;lich (458752 cores) and the complete Mira at Argonne National Laboratory (786432 cores).<\/jats:p>","DOI":"10.3233\/978-1-61499-621-7-797","type":"book-chapter","created":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T15:30:51Z","timestamp":1739979051000},"source":"Crossref","is-referenced-by-count":1,"title":["FE"],"prefix":"10.3233","author":[{"family":"Klawonn Axel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Lanser Martin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"family":"Rheinbach Oliver","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Advances in Parallel Computing","Parallel Computing: On the Road to Exascale"],"original-title":[],"deposited":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T15:42:55Z","timestamp":1739979775000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISBN&isbn=978-1-61499-620-0&spage=797&doi=10.3233\/978-1-61499-621-7-797"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-621-7-797","relation":{},"ISSN":["0927-5452"],"issn-type":[{"value":"0927-5452","type":"print"}],"subject":[],"published":{"date-parts":[[2016]]}}}
