In most places, we did not advance the passive scalar computation for new code versions, it is mainly untested in FSI computation, also in backuping/resume
so, before using the passive scalar seriously, be sure to update the code accordingly.
it might also be better to merge pseudospectators/MISTRALs FD-based RHS at some point, since it is a huge waste of resources to compute the passive scalar with Fourier methods (it does not involve a Poisson eqn!)
