Dynamical continuum simulation of condensed matter from first-principles
Oliver Strickson, Nikos Nikiforakis, Emilio Artacho
Macroscale continuum mechanics simulations rely on material properties stemming from the microscale, which are normally described using phenomenological equations of state (EOS). A…
A unified Eulerian framework for multimaterial continuum mechanics
Haran Jackson, Nikos Nikiforakis
A framework for simulating the interactions between multiple different continua is presented. Each constituent material is governed by the same set of equations, differing only in…
Fast Distance Fields for Fluid Dynamics Mesh Generation on Graphics Hardware
A. Roosing, O. T. Strickson, N. Nikiforakis
We present a CUDA accelerated implementation of the Characteristic/Scan Conversion algorithm to generate narrow band signed distance fields in logically Cartesian grids. We outline…
A Numerical Scheme for Non-Newtonian Fluids and Plastic Solids under the GPR Model
Haran Jackson, Nikos Nikiforakis
A method for modelling non-Newtonian fluids (dilatants and pseudoplastics) by a power law under the Godunov-Peshkov-Romenski model is presented, along with a new numerical scheme f…
A dimensionally split Cartesian cut cell method for the compressible Navier-Stokes equations
Nandan Gokhale, Nikos Nikiforakis, Rupert Klein
We present a dimensionally split method for computing solutions to the compressible Navier-Stokes equations on Cartesian cut cell meshes. The method is globally second order accura…
A dimensionally split Cartesian cut cell method for hyperbolic conservation laws
Nandan Gokhale, Nikos Nikiforakis, Rupert Klein
We present a dimensionally split method for solving hyperbolic conservation laws on Cartesian cut cell meshes. The approach combines local geometric and wave speed information to d…
A Moving Boundary Flux Stabilization Method for Cartesian Cut-Cell Grids using Directional Operator Splitting
W. P. Bennett, N. Nikiforakis, R. Klein
An explicit moving boundary method for the numerical solution of time-dependent hyperbolic conservation laws on grids produced by the intersection of complex geometries with a regu…
