An Efficient Linearity and Bound Preserving Conservative Interpolation (Remapping) on Polyhedral Meshes
An accurate conservative interpolation (remapping) algorithm is an essential component of most ALE methods. The presented algorithm on 3D polyhedral meshes is based on reconstruction, approximate integration and conservative

Optimization-based synchronized flux-corrected conservative interpolation (remapping) of mass and momentum for arbitrary lagrangian-eulerian methods
A new optimization-based synchronized flux-corrected conservative interpolation (remapping) of mass and momentum for arbitrary Lagrangian-Eulerian hydro methods is described. Fluxes of conserved variables - mass and momentu...

An efficient linearity-and-bound-preserving remapping method
In this paper we describe an efficient, local-bound-preserving conservative interpolation (remapping) algorithm, which is exact for a global linear function (linearity-preserving). The algorithm is based on reconstruction, approxima...

Flux-Based Approach for Conservative Remap of Multi-Material Quantities in 2D Arbitrary Lagrangian-Eulerian Simulations
Remapping is one of the essential parts of most Arbitrary Lagrangian-Eulerian (ALE) methods. It conservatively interpolates all fluid quantities from the original (Lagrangian) computational mesh to the new (rezoned) one. This paper ...

Bound-preserving remapping of staggered quantities for multi-material ALE methods
In Arbitrary Lagrangian-Eulerian (ALE) methods, remap is one of the key steps necessary for conservative interpolation of all fluid quantities between the computational meshes. We are mostly interested in the remap in the case of mu...

Reduced-dissipation remapping of velocity in staggered arbitrary Lagrangian-Eulerian methods
In this paper, we focus on the part of the remapping algorithm that performs the interpolation of the fluid velocity field from the Lagrangian to the rezoned computational mesh in the context of a staggered discretization. We analyze the app...

Sequential Flux-Corrected Remapping for ALE Methods
A new FCT-based algorithm is presented for conservative, local bounds preserving interpolations, necessary in the remapping step of Arbitrary Lagrangian-Eulerian (ALE) simulations. To avoid overrestriction of high-order fluxes, caus...
