Nonsymmetric multigrid preconditioning for conjugate gradient methods
Henricus Bouwmeester, Andrew Dougherty, Andrew V. Knyazev
We numerically analyze the possibility of turning off post-smoothing (relaxation) in geometric multigrid when used as a preconditioner in conjugate gradient linear and eigenvalue s…

The initial growth of sidebranches in ammonium chloride dendrites
Andrew Dougherty
We report measurements for the initial stages of sidebranching during the dendritic growth of ammonium chloride from supersaturated aqueous solution. The earliest sidebranches are…

Measurement of the Capillary Length for the Dendritic Growth of Ammonium Chloride
Andrew Dougherty
We report the results of a new method of measuring the capillary length for the dendritic crystal growth of non-faceted materials. This method uses a nearly spherical crystal held…
