Adaptive mesh refinement for numerical simulation of MHD instabilities in tokamaks: JOREK code

Raffinement de maillage adaptatif pour la simulation numérique des instabilités MHD dans les tokamaks : le code JOREK

Abstract

The purpose of this paper is to illustrate both validity and advantages of the implementation of the adaptive mesh raffinement strategy in the recent version of the 3D non-linear MHD code JOREK which uses a technique based on the bicubic Bezier surfaces developed in the paper of Czarny-Huijsmans. We describe the physcal model and establish a refinement criteria. Then, we also present the numerical results of adaptive mesh raffinement simulation for the a tearing instability test case and to the test case of injection mechanism of a small pellet of frozen hydrogen into a tokamak.
