Modeling anisotropic Material

hi,

i need to model a system (a sphere with a dipole in its centre), the model exhibits anisotropic conductivity. i.e. the radial value of electrical conductivity sigma is 10 times less than its tengentational counterpart. i have the local values of these conductivities, my question is whether femlab/comsol accept values of conductivity tensor in local or gloable coordinates. and is there a way to translate local coordinates into global one.
