A software framework for embedded nonlinear model predictive control using a gradient-based augmented Lagrangian approach (GRAMPC) [PDF]
A nonlinear MPC framework is presented that is suitable for dynamical systems with sampling times in the (sub)millisecond range and that allows for an efficient implementation on embedded hardware.

Numerical study on the hot compression test for bulk metal forming application
Article highlights Cylindrical compression test is modeled by finite element method and compared with experimental results. The Lagrangian and the Arbitrary Lagrangian–Eulerian (ALE) approaches are used to model the experiments.

Improving collisional growth in Lagrangian cloud models: development and verification of a new splitting algorithm [PDF]
Lagrangian cloud models (LCMs) are increasingly used in the cloud physics community. They not only enable a very detailed representation of cloud microphysics but also lack numerical errors typical for most other models.

A Review of CO2 Plume Dispersion Modeling for Application to Offshore Carbon Capture and Storage
The exponential increase in greenhouse gas emissions necessitates urgent measures to mitigate climate change impacts. Carbon capture and storage (CCS) has emerged as a promising solution, capturing CO2 from industrial processes and storing it underground.

Limiting absorption principle on Riemannian scattering (asymptotically conic) spaces, a Lagrangian approach [PDF]
We use a Lagrangian perspective to show the limiting absorption principle on Riemannian scattering, i.e. asymptotically conic, spaces, and their generalizations.

Spectral-clustering approach to Lagrangian vortex detection [PDF]
One of the ubiquitous features of real-life turbulent flows is the existence and persistence of coherent vortices. Here we show that such coherent vortices can be extracted as clusters of Lagrangian trajectories. We carry out the clustering on a weighted graph, with the weights measuring pairwise distances of fluid trajectories in the extended phase ...

Topological sensitivities via a Lagrangian approach for semilinear problems [PDF]
In this paper we present a methodology that allows the efficient computation of the topological derivative for semilinear elliptic problems within the averaged adjoint Lagrangian framework.

Numerical models are associated with uncertainties that can be reduced through data assimilation (DA). Lower costs have driven a recent tendency to use Lagrangian instruments such as drifters and floats to obtain information about water bodies.

A Backwards-Tracking Lagrangian-Eulerian Method for Viscoelastic Two-Fluid Flows
A new Lagrangian–Eulerian method for the simulation of viscoelastic free surface flow is proposed. The approach is developed from a method in which the constitutive equation for viscoelastic stress is solved at Lagrangian nodes, which are convected by ...
