MHDT is a pseudo-spectral code designed to study incompressible MHD turbulence in a box- or slab-shaped simulation volume. Time integration in MHDT is accomplished with either a Leapfrog scheme or a low-storage 3rd order Runge Kutta scheme. MHDT includes Lagrangian tracer particles to allow for the study of Lagrangian statistics. The velocities of Lagrangian tracer particles are interpolated using a tricubic interpolation from the Eulerian velocity field. MHDT includes packages that allow for a large number of forcing methods to be examined. in addition, the MHD system can optionally be driven by Boussinesq convection.
Early development of MHDT took place at the Max-Planck Institut für Plasmaphysik Garching. MHDT is now primarily developed at the Zentrum für Astronomie und Astrophysik at the TU Berlin.
