Abstract A multi-step Lagrangian scheme at discrete times is proposed for the approximation of a nonlinear continuity equation arising as mean-field limit spatially inhomogeneous evolutionary games, describing evolution system distributed agents with strategies, or labels, whose payoff depends also on current position agents. The Lagrangian, it traces and labels along characteristics, scheme, d...

the purpose of this paper is to investigate the egm method and the behavior of a solid particle suspended in a twodimensional rectangular cavity due to conjugate natural convection. a thermal lattice boltzmann bgk model is implemented to simulate the two dimensional natural convection and the particle phase was modeled using the lagrangian–lagrangian approach where the solid particles are treat...

A comprehensive benchmarking study has been carried out to determine the influence of mesh formulation and chip separation methods on reliability accuracy finite element modelling large diameter drilling operations. The Coupled Eulerian–Lagrangian updated-Lagrangian (with deletion) formulations available in ABAQUS/Explicit, together with re-meshing) DEFORM 3D are compared by simulating through-...

In this paper, we present a conservative cell-centered Lagrangian Finite Volume scheme for solving the hyperelasticity equations on unstructured multidimensional grids. The starting point of approach is FV discretization named EUCCLHYD and introduced in context hydrodynamics. Here, it combined with posteriori Multidimensional Optimal Order Detection (MOOD) limiting strategy to ensure robustness...

We introduce a twice differentiable augmented Lagrangian for nonlinear optimization with general inequality constraints and show that strict local minimizer of the original problem is an approximate solution Lagrangian. A novel method multipliers (ALM) then presented. Our originated from generalization Hestenes-Powell Lagrangian, combination interior-point technique. It shares similar algorithm...

this paper presents results of applying a new approach on 2d inversion of magnetotelluric (mt) data in order to enhance resolution and stability of the inversion results. due to non-linearity and limited coverage of data acquisition in an mt field campaign, minimizing the error by linearization of the problem in least squares inversion usually leads to an ill-posed problem. in general, an inver...
