A Probabilistic Cut Finite Element Method With Random Field Generator and Bayesian Model Calibration for Flow Through Rough Cracks

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 1, Page 298-320, January 2026.
ABSTRACT A new model for the simulation of fluid flow through rough cracks is presented. The model combines a probabilistic cut finite element method (PCutFEM) to capture the unfitted boundary condition at the fluid interface, with a stochastic random field generator to represent the crack asperities.

Numerical Instability in Slope Stability Analysis: A Finite Difference Approach

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 1, Page 536-557, January 2026.
ABSTRACT In geotechnical engineering, slice methods are the most widely used computational techniques for analyzing slope stability. Notably, the Morgenstern‐Price and Janbu approaches rigorously enforce the equilibrium of forces and moments within these slice methods.

On the Stability Barrier of Hermite Type Discretizations of Advection Equations

open access: yesNumerical Methods for Partial Differential Equations, Volume 42, Issue 1, January 2026.
ABSTRACT We establish a stability barrier for a class of high‐order Hermite‐type discretization of 1D advection equations underlying the hybrid‐variable (HV) and active flux (AF) methods. These methods approximate both cell averages and nodal solutions and evolve them in time simultaneously.

Numerical Simulation of Three‐Dimensional Unsteady Extrudate Swell Through Annular Dies: Effects of Die Core Opening Position and Sag on Parison Formation

open access: yesPolymer Engineering &Science, Volume 66, Issue 1, Page 105-121, January 2026.
Study on transient parison formation at various strokes during extrusion of Newtonian and viscoelastic fluids. In the presence of an offset between the mandrel and the bushing, Newtonian fluids exhibit a reduction in extrudate diameter, whereas viscoelastic fluids display diameter swelling only at flow rates exceeding a critical threshold.
