Query: (3+1)-dimensional dissipative relativistic fluid dynamics at non-zero
  net baryon density   Heavy-ion collisions at center-of-mass energies between 1 and 100 GeV/nucleon
are essential to understand the phase diagram of QCD and search for its
critical point. At these energies the net baryon density of the system can be
high, and simulating its evolution becomes an indispensable part of theoretical
modeling. We here present the (3+1)-dimensional diffusive relativistic
hydrodynamic code BEShydro which solves the equations of motion of second-order
Denicol-Niemi-Molnar-Rischke (DNMR) theory, including bulk and shear viscous
currents and baryon diffusion currents. BEShydro features a modular structure
that allows to easily turn on and off baryon evolution and different
dissipative effects and thus to study their physical effects on the dynamical
evolution individually. An extensive set of test protocols for the code,
including several novel tests of the precision of baryon transport that can
also be used to test other such codes, is documented here and supplied as a
permanent part of the code package.
