Object-oriented Pseudo-spectral code TARANG for turbulence simulation

In this paper we describe the design and implementation of TARANG, a pseudospectral code to simulate turbulent flows in fluids, magnetohydrodynamics (MHD), convection, passive scalar, etc. We use the object-oriented features of C++ to abstract operations involved in the simulation. TARANG has been validated and used for solving problems in convection and MHD.
