A Bifidelity Proximal Quasi-Newton Method for Dense Rigid Body Suspension Collision Resolution
Nicholas Rummel, Tyler Jensen, Stephen Becker +1
Direct numerical simulation of dense rigid body suspensions poses significant computational challenges. A popular approach to resolve collisions necessitates solving a linear compl…
DAE Index Reduction for Electromagnetic Transient Models
Fiona Majeau, Jose Daniel Lara, Eduardo Corona +1
Electromagnetic transient (EMT) models are index-2 differential-algebraic equations when they include certain topologies and are formulated with modified nodal analysis. Such syste…
A Mass Preserving Numerical Scheme for Kinetic Equations that Model Social Phenomena
Yassin Bahid, Eduardo Corona, Nancy Rodriguez
In recent years, kinetic equations have been used to model many social phenomena. A key feature of these models is that transition rate kernels involve Dirac delta functions, which…
Tensor-Train Compression of Discrete Element Method Simulation Data
Saibal De, Eduardo Corona, Paramsothy Jayakumar +1
We propose a framework for discrete scientific data compression based on the tensor-train (TT) decomposition. Our approach is tailored to handle unstructured output data from discr…
Fast and accurate solvers for simulating Janus particle suspensions in Stokes flow
Ryan Kohl, Eduardo Corona, Vani Cheruvu +1
We present a novel computational framework for simulating suspensions of rigid spherical Janus particles in Stokes flow. We show that long-range Janus particle interactions for a w…
A scalable computational platform for particulate Stokes suspensions
Wen Yan, Eduardo Corona, Dhairya Malhotra +2
We describe a computational framework for simulating suspensions of rigid particles in Newtonian Stokes flow. One central building block is a collision-resolution algorithm that ov…
Tensor Train accelerated solvers for nonsmooth rigid body dynamics
Eduardo Corona, David Gorsich, Paramsothy Jayakumar +1
In the last two decades, increased need for high-fidelity simulations of the time evolution and propagation of forces in granular media has spurred renewed interest in discrete ele…
Boundary integral equation analysis for suspension of spheres in Stokes flow
Eduardo Corona, Shravan Veerapaneni
We show that the standard boundary integral operators, defined on the unit sphere, for the Stokes equations diagonalize on a specific set of vector spherical harmonics and provide…
An integral equation formulation for rigid bodies in Stokes flow in three dimensions
Eduardo Corona, Leslie Greengard, Manas Rachh +1
We present a new derivation of a boundary integral equation (BIE) for simulating the three-dimensional dynamics of arbitrarily-shaped rigid particles of genus zero immersed in a St…
A Tensor-Train accelerated solver for integral equations in complex geometries
Eduardo Corona, Abtin Rahimian, Denis Zorin
We present a framework using the Quantized Tensor Train (QTT) decomposition to accurately and efficiently solve volume and boundary integral equations in three dimensions. We descr…
An O(N) Direct Solver for Integral Equations on the Plane
Eduardo Corona, Per-Gunnar Martinsson, Denis Zorin
An efficient direct solver for volume integral equations with O(N) complexity for a broad range of problems is presented. The solver relies on hierarchical compression of the discr…
