  Dynamics of an anisotropic universe is studied in $f(R,T)$ gravity using a
rescaled functional $f(R,T)$. Three models have been constructed assuming a
power law expansion of the universe. Physical features of the models are
discussed. The model parameters are constrained from a dimensional analysis. It
is found from the work that, the $BVI_h$ model in the modified gravity can
favour quintessence and phantom phase.
