Abstract : A method for solving the complete set of multifluid MHD equations is given. The algorithm SLIDE, which is derived from flux corrected transport methods, is used to solve the fluid equations on a moving 2D axisymmetric coordinate grid in which one set of grid lines represents magnetic flux surfaces while a second set is constructed orthogonal. Preservation of the diagonal form of transport tensors allows accurate representation of anisotropic transport. Results are shown for a problem in theta-pinch geometry and are contrasted to the results of a more conventional (r,z) code. (Author)
