Using Animated Textures to Visualize Electromagnetic Fields and Energy Flow

Posted by klaurent MIT

Kavli Affiliate: John Belcher | Summary:Animated textures can be used to visualize the spatial structure and temporal evolution of vector fields at high spatial resolution. The animation requires two time-dependent vector fields. The first of these vector fields determines the spatial structure to be displayed. The second is a velocity field that determines the time […]

A spectral Galerkin method for the coupled Orr-Sommerfeld and induction equations for free-surface MHD

Posted by klaurent Chicago

Kavli Affiliate: Robert Rosner | Summary:We develop and test spectral Galerkin schemes to solve the coupled Orr-Sommerfeld (OS) and induction equations for parallel, incompressible MHD in free-surface and fixed-boundary geometries. The schemes’ discrete bases consist of Legendre internal shape functions, supplemented with nodal shape functions for the weak imposition of the stress and insulating boundary […]
