New simulation capabilities in HYDRA**

The ability of HYDRA to simulate indirect drive, direct drive and magnetic drive targets has been enhanced with the addition a several new capabilities.  A new multiresolution advection capability which eliminates any need to remap calculations to a new mesh topology during the run. We describe the improved performance obtained with this new method.  A new inline model for stimulated Brillouin scattering (SBS) has been implemented.  The model integrates the coupled-mode equations for SBS gain and inverse bremsstrahlung absorption along the rays.  It can be run in conjunction with the inline SRS model and the model for cross beam energy transfer.  A low noise inverse-projection method has been extended to the 3-D laser raytrace package.  It reduces ray deposition noise, while allowing direct drive targets to be modelled with only a fraction of the rays of the conventional method.  The MHD package can now run effective 2D problems faster with the addition of a new dedicated 2D solver option.  The Monte Carlo transport package now includes the effect of magnetic fields on charged particle orbits.  We discuss these and other new capabilities.
