  In radio-loud active galactic nuclei (AGNs), ultra-fast outflows (UFOs) were
detected at the inclination angle of $\sim10^{\rm o}$--$70^{\rm o}$ away from
jets. Except for the inclination angle of UFOs, the UFOs in radio-loud AGNs
have similar properties to that in radio-quiet AGNs. The UFOs with such low
inclination cannot be explained in the line-force mechanism. The
magnetic-driving mechanism is suggested to explain the UFOs based on a
self-similar solution with radiative transfer calculations. However, the
energetics of self-similar solution need to be further confirmed based on
numerical simulations. To understand the formation and acceleration of UFOs in
radio-loud AGNs, this paper presents a model of the disk winds driven by both
line force and magnetic field and implements numerical simulations. Initially,
a magnetic field is set to 10 times stronger than the gas pressures at the disk
surface. Simulation results imply that the disk winds driven by both line force
and magnetic field could describe the properties of UFOs in radio-loud AGNs.
Pure magnetohydrodynamics (MHDs) simulation is also implemented. When the
initial conditions are the same, the hybrid models of magnetic fields and line
force are more helpful to form UFOs than the pure MHD models. It is worth
studying the case of a stronger magnetic field to confirm this result.
