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
