A Viscoelastic Catastrophe
Kristian Ejlebjerg Jensen, Peter Szabo, Fridolin Okkels
We use a differential constitutive equation to model the flow of a viscoelastic flow in a cross-slot geometry, which is known to exhibit bistability above a critical flow rate. The…
Simulating Viscous Fingering with a Timespace Method and Anisotropic Mesh Adaptation
Kristian E. Jensen
We report findings related to a two dimensional viscous fingering problem solved with a timespace method and anisotropic elements. Timespace methods have attracted interest for sol…
Implementation of the Log-Conformation Formulation for Two-Dimensional Viscoelastic Flow
K. E. Jensen, P. Szabo, F. Okkels
We have implemented the log-conformation method for two-dimensional viscoelastic flow in COMSOL, a commercial high-level finite element package. The code is verified for an Oldroyd…
Thread Parallelism for Highly Irregular Computation in Anisotropic Mesh Adaptation
Georgios Rokos, Gerard J. Gorman, Kristian Ejlebjerg Jensen +1
Thread-level parallelism in irregular applications with mutable data dependencies presents challenges because the underlying data is extensively modified during execution of the al…
Solving Stress and Compliance Constrained Volume Minimization using Anisotropic Mesh Adaptation, the Method of Moving Asymptotes and a Global p-norm
Kristian Jensen
The p-norm often used in stress constrained topology optimisation supposedly mimics a delta function and it is thus characterised by a small length scale and ideally one would also…
