Abstract
A particular configuration of the LHD stellarator with an unusually fl at pressure profile has been chosen to be a test case for comparison o f the MHD stability property predictions of different three-dimensiona l and averaged codes for the purpose of code comparison and validation . In particular, two relatively localized instabilities, the fastest g rowing modes with toroidal mode numbers n = 2 and n = 3, were studied using several different codes, with the good agreement that has been f ound providing justification for the use of any of them for equilibria of the type considered.
