Higher-Order Discontinuous Galerkin Splitting Schemes for Fluids with Variable Viscosity
Richard Schussnig, Niklas Fehn, Douglas Ramalho Queiroz Pacheco +1
This article investigates matrix-free higher-order discontinuous Galerkin discretizations of the Navier--Stokes equations for incompressible flows with variable viscosity. The visc…
A consistent diffuse-interface finite element approach to rapid melt--vapor dynamics with application to metal additive manufacturing
Magdalena Schreter-Fleischhacker, Nils Much, Peter Munch +3
Metal additive manufacturing via laser-based powder bed fusion (PBF-LB/M) faces performance-critical challenges due to complex melt pool and vapor dynamics, often oversimplified by…
Matrix-Free Higher-Order Finite Element Methods for Hyperelasticity
Richard Schussnig, Niklas Fehn, Peter Munch +1
This work presents a matrix-free finite element solver for finite-strain elasticity adopting an -multigrid preconditioner. Compared to classical algorithms relying on a global…
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…
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…
