The current state of the art in pulsar magnetospheric modeling assumes the force-free limit of magnetospheric plasma. This limit retains only partial information about plasma velocity and neglects plasma inertia and temperature. We carried out time-dependent 3D relativistic magnetohydrodynamic (MHD) simulations of oblique pulsar magnetospheres that improve upon force-free by retaining the full plasma velocity information and capturing plasma heating of putative magnetospheric gamma-ray emission regions. We present the velocity structure in an oblique pulsar magnetosphere and the dependence of pulsar spindown power on inclination.
