Smart Plates: Reduced Models and Numerical Simulations

Abstract: In this paper asymptotic models describing the mechanical and electric equilibrium state of two types of smart structures are presented and justified. The first structure consists of an anisotropic elastic thin plate with two surface bonded anisotropic piezoelectric patches and the second one is an anisotropic elastic sandwich thin plate with an inserted anisotropic piezoelectric patc...

Drift Wave Simulations with Reduced Stellarator Equilibria

A three-field model to study drift-resistive, low-frequency waves in low-β, non-axisymmetric plasmas [J.L.V. Lewandowski, Phys. Plasmas, 4(11) 4023 (1997)] is used to analyze the effect of the inhomogeneities in the stellarator magnetic field on the fastest (linear) growth rate, γ. Extensive numerical calculations for a toroidal heliac show that not all Fourier components in the representation ...

Multiscale S-Fraction Reduced-Order Models for Massive Wavefield Simulations

Benchmarking the generalized Rutherford equation with reduced MHD simulations

Introduction The nonlinear growth of neoclassical tearing modes (NTMs) in tokamaks is commonly discussed in the framework of the generalized Rutherford equation (GRE) [1, 2]. We perform a theoretical / numerical validation of the GRE by means of numerical simulations implementing the set of 2D reduced MHD equations for the helical magnetic flux ψ and the potential φ [3]. The code uses finite di...

Enabling Interactive Mobile Simulations Through Distributed Reduced Models

Currently, various hardware and software companies are developing augmented reality devices, most prominently Microsoft with its Hololens. Besides gaming, such devices can be used for serious pervasive applications, like interactive mobile simulations to support engineers in the field. Interactive simulations have high demands on resources, which the mobile device alone is unable to satisfy. Th...
