Anaysis of the validity of P2D models for solid-state batteries in a large parameter range
Stephan Sinzig, Christoph P. Schmidt, Wolfgang A. Wall
Simulation models are nowadays indispensable to efficiently assess or optimize novel battery cell concepts during the development process. Electro-chemo-mechano models are widely u…
High-performance matrix-free unfitted finite element operator evaluation
Maximilian Bergbauer, Peter Munch, Wolfgang A. Wall +1
Unfitted finite element methods, like CutFEM, have traditionally been implemented in a matrix-based fashion, where a sparse matrix is assembled and later applied to vectors while s…
A highly efficient computational approach for part-scale microstructure predictions in Ti-6Al-4V additive manufacturing
Sebastian D. Proell, Julian Brotz, Martin Kronbichler +2
Fast and efficient simulations of metal additive manufacturing (AM) processes are highly relevant to exploring the full potential of this promising manufacturing technique. The mic…
A conservative and efficient model for grain boundaries of solid electrolytes in a continuum model for solid-state batteries
Stephan Sinzig, Christoph P. Schmidt, Wolfgang A. Wall
A formulation is presented to efficiently model ionic conduction inside, i.e. across and along, grain boundaries. Efficiency and accuracy is achieved by reducing it to a two-dimens…
Improved accuracy of continuum surface flux models for metal additive manufacturing melt pool simulations
Nils Much, Magdalena Schreter-Fleischhacker, Peter Munch +3
Computational modeling of the melt pool dynamics in laser-based powder bed fusion metal additive manufacturing (PBF-LB/M) promises to shed light on fundamental mechanisms of defect…
A consistent diffuse-interface model for two-phase flow problems with rapid evaporation
Magdalena Schreter-Fleischhacker, Peter Munch, Nils Much +3
We present accurate and mathematically consistent formulations of a diffuse-interface model for two-phase flow problems involving rapid evaporation. The model addresses challenges…
