Borgis, Daniel. We propose an in-silico experiment to introduce classical density functional theory (cDFT). Den- sity functional theories, whether quantum or classical, rely on abstract concepts that are non- intuitive. However, they are at the heart of powerful tools and active fields of research in both physics and chemistry.

Using the optimized geometrical structures, the CDFT descriptors of the reactants in vacuo and in solution were calculated (Table S3), which sets forward a first analysis of their reactivity.

The problem is, I have no idea how to use MPI to parallel the fft part of my code. I included "mkl_cdft.f" and "mpif.h" in my code but I don't know what's the next step. I think I have to add MPI part in my code. Also I have to learn how to link intel compiler with MPI. I've searched for some tutorials but I still have no idea.Conversion table.
