Models of magnetohydrodynamic (MHD) equilibia that for computationalconvenience assume the existence of a system of nested magnetic flux surfacestend to exhibit singular current sheets. These sheets are located on resonantflux surfaces that are associated with rational values of the rotationaltransform. We study the possibility of eliminating these singularities bysuitable modifications of the plasma boundary, which we prescribe in a fixedboundary setting. We find that relatively straightforward iterative procedurescan be used to eliminate weak current sheets that are generated at resonantflux surfaces by the nonlinear interactions of resonating wall harmonics. Thesetypes of procedures may prove useful in the design of fusion devices withconfigurations that enjoy improved stability and transport properties.
