Old-fashioned CPU optimisation of a fluid simulation for investigating turbophoresis

The used spectral code performs Direct Numerical Simulation of particle-laden non-isothermal channel flow at a frictional Reynolds number of 950. It has been parallelized originally with MPI and the number of MPI tasks is limited to 384 because of the 1D domain decomposition. The goal was to increase the performance of the model using a threaded OpenMP approach (strong scaling is used).
