The new model introduces modern computational concepts to achieve excellent performance on parallel computer architectures. Strong scalability was found on ccNUMA architectures underlining maximum parallel efficiency of the implementation. For this purpose, the model considers the application of local level-set functions at the grain level. The model was utilized to simulate ideal and non-ideal grain growth in 2D and 3D with the objective to study the evolution of statistical representative volume elements in polycrystals. The novelty of the proposed level-set approach to grain growth resides in the explicit consideration of structural interfacial elements of the microstructure. The extensions allow to consider anisotropic grain boundary energies and triple junction drag in polycrystalline materials. In addition, microstructure evolution under the influence of secondary driving forces, i.e such as resulting from stored elastic energies or such as occur in anisotropic magnetic materials affected by an external magnetic field, was modeled and simulated considering very large volume elements composed of half a million of grains in 3D. The gain in computational performance is essential to conduct simulation to investigate rare events in microstructure evolution, such as nucleation sites during recrystallization.$$leng 000709678 588__ $$aDataset connected to Lobid/HBZ 000709678 591__ $$aGermany 000709678 653_7 $$agrain growth 000709678 653_7 $$alarge scale simulation 000709678 653_7 $$alevel-set 000709678 653_7 $$amagnetically driven grain boundary motion 000709678 653_7 $$aparallelization 000709678 653_7 $$arecrystallization 000709678 7001_ $$0P:(DE-82)000336$$aGottstein, Günter$$b1$$eThesis advisor 000709678 7001_ $$0P:(DE-82)IDM00070$$aMelcher, Christof$$b2$$eThesis advisor 000709678 7001_ $$0P:(DE-82)IDM00232$$aBleck, Wolfgang$$b3$$eThesis advisor 000709678 8564_ $$uhttps://publications.rwth-aachen.de/record/709678/files/709678.pdf$$yOpenAccess 000709678 8564_ $$uhttps://publications.rwth-aachen.de/record/709678/files/709678_source.zip$$yRestricted 000709678 8564_ $$uhttps://publications.rwth-aachen.de/record/709678/files/709678.gif?subformat=icon$$xicon$$yOpenAccess 000709678 8564_ $$uhttps://publications.rwth-aachen.de/record/709678/files/709678.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000709678 8564_ $$uhttps://publications.rwth-aachen.de/record/709678/files/709678.jpg?subformat=icon-700$$xicon-700$$yOpenAccess 000709678 909CO $$ooai:publications.rwth-aachen.de:709678$$popenaire$$popen_access$$pVDB$$pdriver$$pdnbdelivery 000709678 9101_ $$0I:(DE-588b)36225-6$$6P:(DE-588)1149479760$$aRWTH Aachen$$b0$$kRWTH 000709678 9141_ $$y2017 000709678 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000709678 9201_ $$0I:(DE-82)520000_20140620$$k520000$$lFachgruppe für Materialwissenschaft und Werkstofftechnik$$x1 000709678 9201_ $$0I:(DE-82)523110_20140620$$k523110$$lLehrstuhl für Werkstoffphysik und Institut für Metallkunde und Metallphysik$$x0 000709678 961__ $$c2018-01-19T12:16:20.745294$$x2017-11-30T12:52:52.966623$$z2018-01-19T12:16:20.745294 000709678 9801_ $$aFullTexts 000709678 980__ $$aI:(DE-82)520000_20140620 000709678 980__ $$aI:(DE-82)523110_20140620 000709678 980__ $$aUNRESTRICTED 000709678 980__ $$aVDB 000709678 980__ $$aphd
