Accelerating the computation of FLAPW methods on heterogeneous architectures
Davor Davidović, Diego Fabregat-Traver, Markus Höhnerbach +1
Legacy codes in computational science and engineering have been very successful in providing essential functionality to researchers. However, they are not capable of exploiting the…
A segmentation-free isogeometric extended mortar contact method
Thang Xuan Duong, Laura De Lorenzis, Roger A. Sauer
This paper presents a new isogeometric mortar contact formulation based on an extended finite element interpolation to capture physical pressure discontinuities at the contact boun…
An isogeometric finite element formulation for phase transitions on deforming surfaces
Christopher Zimmermann, Deepesh Toshniwal, Chad M. Landis +3
This paper presents a general theory and isogeometric finite element implementation for studying mass conserving phase transitions on deforming surfaces. The mathematical problem i…
A monolithic fluid-structure interaction formulation for solid and liquid membranes including free-surface contact
Roger A. Sauer, Tobias Luginsland
A unified fluid-structure interaction (FSI) formulation is presented for solid, liquid and mixed membranes. Nonlinear finite elements (FE) and the generalized-alpha scheme are used…
Probing the phonon surface interaction by wave packet simulation: effect of roughness and morphology
Cheng Shao, Qingyuan Rong, Ming Hu +1
One way to reduce the lattice thermal conductivity of solids is to induce additional phonon surface scattering through nanostructures. However, how phonons interact with boundaries…
Non-Linear Least-Squares Optimization of Rational Filters for the Solution of Interior Eigenvalue Problems
Jan Winkelmann, Edoardo Di Napoli
Rational filter functions can be used to improve convergence of contour-based eigensolvers, a popular family of algorithms for the solution of the interior eigenvalue problem. We p…
A Lagrangian approach to modeling heat flux driven close-contact melting
K. Schüller, J. Kowalski
Close-contact melting refers to the process of a heat source melting its way into a phase-change material. Of special interest is the close-contact melting velocity, or more specif…
Decouple Electronic and Phononic Transport in Nanotwinned Structure: A New Strategy for Enhancing the Figure-of-merit of Thermoelectrics
Yanguang Zhou, Xiaojing Gong, Ben Xu +1
Thermoelectrics (TE) materials manifest themselves in direct conversion of temperature differences to electric power and vice versa. Despite remarkable advances have been achieved…
Adaptive local surface refinement based on LR NURBS and its application to contact
Christopher Zimmermann, Roger A. Sauer
A novel adaptive local surface refinement technique based on Locally Refined Non-Uniform Rational B-Splines (LR NURBS) is presented. LR NURBS can model complex geometries exactly a…
The irreversible thermodynamics of curved lipid membranes
Amaresh Sahu, Roger A. Sauer, Kranthi K. Mandadapu
The theory of irreversible thermodynamics for arbitrarily curved lipid membranes is presented here. The coupling between elastic bending and irreversible processes such as intra-me…
