Automated Centerline Extraction From Meshed Vascular Models

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 6, June 2026.
A method to extract centerlines from image‐based vascular meshes is presented, which automatically identifies vascular endpoints and traces centerlines by solving Eikonal equations. Compared to a widely used method, the proposed approach requires less user interaction and demonstrates better robustness on models that contain segmentation artifacts from

A Novel Decomposition‐Based Growth Model for Simulating Stress‐Modulated Spinal Growth

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 6, June 2026.
This study introduces the first decomposition‐based finite‐strain growth model for a simplified Functional Spinal Unit, where growth occurs simultaneously with mechanical loading. The approach eliminates the major physical inconsistency of sequential methods—growth in an artificial stress‐free configuration—while preventing mesh distortion and ...

Computational Rheo‐Hydrodynamic Analysis of Non‐Newtonian Blood Flow Through a Tilted Ellipsoidal Stenosed Vascular Segment

Engineering Reports, Volume 8, Issue 6, June 2026.
Non‐Newtonian blood flow through multiple tilted ellipsoidal stenoses is numerically investigated using the DeKee‐Turcotte‐Papanastasiou model. The results reveal asymmetric velocity fields, elevated wall shear stress, significant pressure drops, and shear‐dependent thermal effects, highlighting the critical hemodynamic risks associated with eccentric ...

Evaluation of Modeling Assumptions for Predicting Structural Damage and Train Derailment Under Earthquake Loading

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 7, Page 1514-1532, June 2026.
ABSTRACT The rapid development of new railway networks and the aging of existing infrastructure in seismic‐prone regions continue to motivate the need for efficient methods to simulate the dynamic behavior of coupled train track structure systems. While detailed train–structure interaction (TSI) models can capture complex mechanisms, they are often too

Efficient Numerical Framework for Geothermal Energy Production Optimization in Fracture‐Controlled Reservoirs

International Journal for Numerical Methods in Fluids, Volume 98, Issue 6, Page 709-730, June 2026.
We introduce an efficient open‐source numerical framework for the automated search for the placements of injection and production wells in hot fracture‐controlled reservoirs that sustainably optimize geothermal energy production. We model the reservoirs as discrete fracture networks in 3D. The fluid flow and heat transport in the reservoirs are modeled
