High order stochastic transport and Lagrangian data assimilation
… matter, etc.). Understanding such uncertain Lagrangian transport is imperative for reducing environmental damage due to natural hazards and for allowing rigorous risk analysis and effective search and rescue. While secondary variables and trajectories have classically been used for the …

Finite element modeling of cutting and burnishing processes at micro- and nanoscales
… cutting and micro/nano burnishing processes. The coupled Eulerian-Lagrangian method is used for modeling the micro/nano cutting process to avoid excessive distortion of meshes, while the Lagrangian formulation is used for modeling the micro/nano burnishing process to capture the resulting …

Structural Vulnerability of Coastal Bridges Under Hurricane Conditions
… models were developed within ABAQUS, utilizing a Coupled Eulerian Lagrangian (CEL) analysis, to provide a cost-effective approach for evaluating bridge behavior under various hydrodynamic conditions. An experimental scaled model was used to calibrate numerical models with a range of explicit …

FSI Methodology for Analyzing VIV on Subsea Pipeline Free Spans with Practical Boundary Conditions
… FSI simulations in combination with separate coupled Eulerian-Lagrangian (CEL) simulations are modeled to mimic real world conditions by setting up the boundary conditions to factor in the effects of pipe-soil interaction at the ends of the span. Computational design of experiments (DOE) is …

Multi-scale Finite Element Modeling of Rubber Friction Toward Prediction of Hydroplaning Potential
… two approaches. In the first approach, the coupled Eulerian-Lagrangian (CEL) formulation was used. The drawback associated with the CEL method is the laminar assumption that the behavior of the fluid at length scales smaller than the smallest element size is not captured. To improve the …

Characterization and Modeling of Deformable Soils for Tire Performance Simulations
… for both soils are performed using one meshed (Coupled Eulerian-Lagrangian) and one meshless (Smooth Particle Hydrodynamics) method are performed. The results of the numerical simulations are validated with the experimental data obtained at different normal loads (3 kN - 7 kN) and slip ratios …

Argon bubble transport and capture in continuous casting with an external magnetic field using GPU-based large eddy simulations
… to model the turbulent flow. A two-way coupled Lagrangian particle tracking model is added to track the motion of argon bubbles. A particle/bubble capture model based on force balance at dendrite tips is validated and used to study the capture of argon bubbles by the solidifying steel …

Study of an advanced helmet liner concept to reduce TBI : experiments & simulation using sandwich structures
… carried out. Fluid fillers are modeled using the coupled Eulerian-Lagrangian (CEL) functionality of ABAQUS. Preliminary results using flat plate sandwich structures with rectangular channels show that the use of high density filler material results in higher levels of blast mitigation. The peak …

Modelling the Extrusion of a Hard-Metal Paste
… were performed using ABAQUS® with an Arbitrary Lagrangian-Eulerian (ALE) formulation and custom friction subroutines. Steady-state velocity profiles and the pressure drop through square-entry geometries were predicted and extended to the extrusion of MCC/CaCO3 through conical-entry and 3D …

High Order Explicit Semi-Lagrangian Method for the Solution of Lagrangian Transport and Stochastic Differential Equations
<p>A semi-Lagrangian method is developed for the solution of Lagrangian transport equations and stochastic differential equations that is consistent with Discontinuous Spectral Element Method (DSEM) approximations of Eulerian conservation laws. The method extends the favorable properties of DSEM …
