Parallelized Domain Decomposition for Multi-Dimensional Lagrangian Random Walk, Mass-Transfer Particle Tracking Schemes

Lucas Schauer, Michael J. Schmidt, Nicholas B. Engdahl +3

We develop a multi-dimensional, parallelized domain decomposition strategy (DDC) for mass-transfer particle tracking (MTPT) methods. These methods are a type of Lagrangian algorith…

A Computational Information Criterion for Particle-Tracking with Sparse or Noisy Data

Nhat Thanh Tran, David A. Benson, Michael J. Schmidt +1

Traditional probabilistic methods for the simulation of advection-diffusion equations (ADEs) often overlook the entropic contribution of the discretization, e.g., the number of par…

Nonparametric, data-based kernel interpolation for particle-tracking simulations and kernel density estimation

David A Benson, Diogo Bolster, Stephen Pankavich +1

Traditional interpolation techniques for particle tracking include binning and convolutional formulas that use pre-determined (i.e., closed-form, parameteric) kernels. In many inst…

A Mass-transfer Particle-tracking Method for Simulating Transport with Discontinuous Diffusion Coefficients

Michael J. Schmidt, Nicholas B. Engdahl, Stephen D. Pankavich +1

The problem of a spatially discontinuous diffusion coefficient () is one that may be encountered in hydrogeologic systems due to natural geological features or as…

Reactive Particle-tracking Solutions to a Benchmark Problem on Heavy Metal Cycling in Lake Sediments

Michael J. Schmidt, Stephen D. Pankavich, Alexis Navarre-Sitchler +3

Geochemical systems are known to exhibit highly variable spatiotemporal behavior. This may be observed both in non-smooth concentration curves in space for a single sampling time a…

Numerical Equivalence Between SPH and Probabilistic Mass Transfer Methods for Lagrangian Simulation of Dispersion

Guillem Sole-Mari, Michael J. Schmidt, Stephen D. Pankavich +1

Several Lagrangian methodologies have been proposed in recent years to simulate advection-dispersion of solutes in fluids as a mass exchange between numerical particles carrying th…
