GYRO: A 5-D Gyrokinetic-Maxwell Solver
GYRO solves the 5-dimensional gyrokinetic-Maxwell equations in shaped plasma geometry, using either a local (fluxtube) or global radial domain. It has been ported to a variety of...

A Comparison of Inexact Newton and Coordinate Descent Mesh Optimization Techniques
We compare inexact Newton and coordinate descent methods for optimizing the quality of a mesh by repositioning the vertices, where quality is measured by the harmonic mean of the ...

Mesh Graph Structure for Longest-Edge Refinement Algorithms
In this paper we introduce and discuss a graph structure associated with longest-edge algorithms (algorithms based on the bisection of triangles by the longest-edge) which can be u...
