Comparison of the Particle Finite Element Method (PFEM) and Finite Element Method (FEM) on a Linear Elastic Heterogeneous Test Specimen

PAMM, Volume 25, Issue 4, December 2025.
ABSTRACT In industrial manufacturing, large share of machining tools are produced using materials such as tungsten carbide, due to their exceptional properties. However, they are now classified as critical, due to the limited availability of constituents and the accompanying social‐environmental concerns related to their mining and processing.

Adaptive smoothed FEM for forming simulations [PDF]

, 2012
FEMsimulation of large deformations as occur in metal forming processes is usually accompanied with highly distorted meshes. This leads first to a reduction of accuracy and later to loss of convergence when implicit solvers are used.

A Distributed‐Heterogeneous Design for Explicit Hyperbolic Solvers. Application to Tsunami Urban Run‐Up Modelling

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 12, December 2025.
Abstract A distributed multi‐architecture design for massively parallel hyperbolic solvers is herein introduced and benchmarked. A unified object‐oriented central processing unit (CPU) + graphics processing unit (GPU) approach is complemented with an inter‐device communication layer, enabling both coarse and fine‐grain parallelism on hyperbolic solvers.

Quantifying the Influence of Fault Geometry via Mesh Morphing With Applications to Earthquake Dynamic Rupture and Thermal Models of Subduction

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract Subsurface geometries, such as faults and subducting slab interfaces, are often poorly constrained, yet they exert first‐order control on key geophysical processes, including subduction zone thermal structure and earthquake rupture dynamics.

A Computational Multiscale Framework for Bone Remodeling: Coupling Apparent Density Evolution and Microscale Shape Optimization

International Journal for Numerical Methods in Biomedical Engineering, Volume 41, Issue 10, October 2025.
This study introduces a multiscale patient‐specific framework that couples mechano‐biological bone remodeling at the macroscale with microscale shape optimization. The framework is validated through literature case studies and demonstrates how remodeling influences vertebral fracture behavior.
