The paper demonstrates how the minimisation of an appropriate energy functional can be used to determine 3D magnetohydrodynamic (MHD) equilibria with anisotropic pressure. The flux surface average of the radial MHD force balance relation is shown to relate to the Grad-Schlüter-Shafranov equation. This formulation lends itself to an easy adaptation of the techniques that led to the development of the preconditioned VMEC code for scalar pressure equilibria. A fixed boundary calculation in an ATF torsatron configuration is considered, as a sample application of the method.
