Initial Data for General Relativity Containing a Marginally Outer Trapped Torus [PDF]
, 1996 Asymptotically flat, time-symmetric, axially symmetric and conformally flat initial data for vacuum general relativity are studied numerically on $R^3$ with the interior of a standard torus cut out.

Optimising Spatial and Tonal Data for PDE-based Inpainting
, 2015 Some recent methods for lossy signal and image compression store only a few selected pixels and fill in the missing structures by inpainting with a partial differential equation (PDE).

ISIS: a new N-body cosmological code with scalar fields based on RAMSES. Code presentation and application to the shapes of clusters [PDF]
, 2014 Several extensions of the standard cosmological model include scalar fields as new degrees of freedom in the underlying gravitational theory. A particular class of these scalar field theories include screening mechanisms intended to hide the scalar field

A Time‐Adaptive Multirate Quasi‐Newton Waveform Iteration for Coupled Problems
International Journal for Numerical Methods in Engineering, Volume 126, Issue 12, 30 June 2025.ABSTRACT We consider waveform iterations for dynamical coupled problems, or more specifically, PDEs that interact through a lower‐dimensional interface. We want to allow for the reuse of existing codes for the subproblems, called a partitioned approach.

Multiphysics Simulation Methods in Computer Graphics
Computer Graphics Forum, Volume 44, Issue 2, May 2025.Abstract Physics simulation is a cornerstone of many computer graphics applications, ranging from video games and virtual reality to visual effects and computational design. The number of techniques for physically‐based modeling and animation has thus skyrocketed over the past few decades, facilitating the simulation of a wide variety of materials and ...

Multi-frame scene-flow estimation using a patch model and smooth motion prior [PDF]
, 2010 This paper addresses the problem of estimating the dense 3D motion of a scene over several frames using a set of calibrated cameras. Most current 3D motion estimation techniques are limited to estimating the motion over a single frame, unless a strong ...

FFT‐Based Phase‐Field Fracture Modeling of Periodic Inhomogeneous Microstructures
Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 4, Page 1782-1805, April 2025.ABSTRACT The failure of inhomogeneous microstructures is of increasing relevance, driven by the future need for tailored materials and the significant influence of microstructure on macroscopic properties. The phase‐field method for fracture has proven to be a versatile tool for predicting unknown crack paths and failure mechanisms.
