Denoising Particle-In-Cell Data via Smoothness-Increasing Accuracy-Conserving Filters with Application to Bohm Speed Computation
Matthew J. Picklo, Qi Tang, Yanzeng Zhang +2
The simulation of plasma physics is computationally expensive because the underlying physical system is of high dimensions, requiring three spatial dimensions and three velocity di…
Superconvergence and accuracy enhancement of discontinuous Galerkin solutions for Vlasov-Maxwell equations
Andrés Galindo-Olarte, Juntao Huang, Jennifer K. Ryan +1
This paper considers the discontinuous Galerkin (DG) methods for solving the Vlasov-Maxwell (VM) system, a fundamental model for collisionless magnetized plasma. The DG methods pro…
Enhanced Multi-Resolution Analysis for Multi-Dimensional Data Utilizing Line Filtering Techniques
Matthew J. Picklo, Jennifer K. Ryan
In this article we introduce Line Smoothness-Increasing Accuracy-Conserving Multi-Resolution Analysis\linebreak (LSIAC-MRA). This is a procedure for exploiting convolution kernel p…
Residual estimates for post-processors in elliptic problems
Andreas Dedner, Jan Giesselmann, Tristan Pryer +1
In this work we examine a posteriori error control for post-processed approximations to elliptic boundary value problems. We introduce a class of post-processing operator that `twe…
Multi-dimensional filtering: Reducing the dimension through rotation
Julia Docampo Sánchez, Jennifer K. Ryan, Mahsa Mirzargar +1
Over the past few decades there has been a strong effort towards the development of Smoothness-Increasing Accuracy-Conserving (SIAC) filters for Discontinuous Galerkin (DG) methods…
Superconvergence properties of an upwind-biased discontinuous Galerkin method
Daniel Frean, Jennifer Ryan
In this paper we investigate the superconvergence properties of the discontinuous Galerkin method based on the upwind-biased flux for linear time-dependent hyperbolic equations. We…
Automated parameters for troubled-cell indicators using outlier detection
Mathea J. Vuik, Jennifer K. Ryan
In Vuik and Ryan (2014) we studied the use of troubled-cell indicators for discontinuity detection in nonlinear hyperbolic partial differential equations and introduced a new multi…
Multiwavelet troubled-cell indicator for discontinuity detection of discontinuous Galerkin schemes
Mathea J. Vuik, Jennifer K. Ryan
In this paper, we introduce a new global troubled-cell indicator for the discontinuous Galerkin (DG) method in one- and two-dimensions. This is done by taking advantage of the glob…
