Elucidating the cellular determinants of the end‐systolic pressure‐volume relationship of the heart via computational modelling

The Journal of Physiology, EarlyView.
Abstract figure legend Using a multiscale computational model of left ventricular electromechanics, we investigated how sarcomere dynamics influence the end‐systolic pressure‐volume (ESPV) relationship in ejecting beats compared to isovolumetric beats.

Computational model of haemodynamics during atrial fibrillation

The Journal of Physiology, EarlyView.
Abstract figure legend We developed a simplified computational model that replicates patient‐specific haemodynamics during both normal sinus rhythm and atrial fibrillation (AF). Our computational model comprises: (1) an electrical subsystem that generates unco‐ordinated atrial and irregular ventricular activation times characteristic of AF and (2) a ...

Stability Optimization of Explicit Runge–Kutta Methods with Higher-Order Derivatives

Algorithms
The paper is devoted to the parametric stability optimization of explicit Runge–Kutta methods with higher-order derivatives. The key feature of these methods is the dependence of the coefficients of their stability polynomials on free parameters.

Model Adjustments and Solver Construction for Galvanic Cells Based on NPP‐Systems

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Electroplated coatings on metallic substrates have a wide range of practical applications ranging from corrosion or wear protection on parts, good conductivity on electrical contacts to coating systems for bipolar plates in fuel cells. The large field of applications in electrochemical engineering motivates several questions for scientific ...

A Two‐Way Coupled Simulation Framework for the Prediction of Fire‐Induced Damage and Smoke Propagation in a Building

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The contribution is concerned with a fully coupled simulation methodology for fire‐induced damage in concrete structures. Fire events in buildings not only generate high temperatures and the spreading of smoke gases but also induce significant structural damages of the concrete structure.

On the Design of Model Predictive Setpoint Controllers for Nonholonomic Multibody Systems

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Systems subject to constraints that are not integrable to position‐level constraints pose significant challenges for setpoint control. In particular, conventional linearization techniques may fail to yield controllable approximations, since certain directions of motion are only accessible through higher‐order interactions of the control inputs.

Efficiency Improvements of RANS-Based Analysis and Optimization using Implicit and Adjoint Methods on Unstructured Grids [PDF]

, 2006
The efficiency of an unstructured grid finite volume RANS solver is signicantly improved using two implicit methods based on diering philosophies. The LU-SGS multigrid method aims to improve performance, while maintaining the low memory requirements and
