High performance computing for flexoelectric devices

This exiting development requires a robust mathematical and computational framework for solving flexoelectric boundary value problems, mathematically a coupled system of 4th-order partial differential equations, in general geometries in 3D. Towards this goal, this thesis presents the implementation...

Descrição
Resumo:This exiting development requires a robust mathematical and computational framework for solving flexoelectric boundary value problems, mathematically a coupled system of 4th-order partial differential equations, in general geometries in 3D. Towards this goal, this thesis presents the implementation of a multi-scale mathematical and computational model for flexoelectricity within a High Performance Computing framework. The model aims to model flexoelectricity in crystalline dielectrics, by solving boundary value problems which couple linear flexoelectricity, piezoelectricity and strain gradient elasticity with unfitted meshes.
