The anisotropy of the magnetoviscous effect in ferrofluids subjected to planar Couette flow is investigated by extensive molecular simulations. The field- and concentration dependence of the viscosity coefficients are found to depend on the relative orientation of the magnetic field with respect to the flow geometry. Comparison with dynamical mean-field models shows satisfactory agreement for moderate interaction strengths. In the semi-dilute regime it is found that the anisotropy contains valuable information on particle interaction. for LaTeX users @article{PIlg2005-71, author = {P. Ilg and M. Kr\"oger and S.
