Due to its high complexity an uniform numerical treatment is impossible. In this work we present a multimethods approach that is based on an asymptotic modeling framework of slender-body theory, homogenization and surrogate models. The algorithm weakly couples melting and spinning phases via iterations. The possibility of combining commercial software and self-implemented code yields satisfying efficiency off-the-shelf. The simulation results are very promising and demonstrate the applicability and practical relevance of our approach for ongoing optimization strategies of the production processes.}, issn = {}, doi = {https://doi.org/}, url = {http://global-sci.org/intro/article_detail/ijnamb/288.html} }
