Is that possbile to use orbital free DFT code to to drive ab initio MD in CP2K?

[Wei Chen]

Orbital free DFT(OFDFT) has quasilinear scaling behaviour.  There has been some softwares proposed on OFDFT, such as PROFESS and DFTpy. Is that possible to merge the OFDFT based software with CP2K ?  Or is there a module that can implement this function in CP2K?

Best wishes,

Hi

there is a OF method in CP2K (DFT/QS/METHOD OFGPW). However,
this has never been used for production and is not actively
developed. It certainly misses many options from state-of-the-art
implementations.
If you just want to use CP2K as a MD driver for an external program,
it will be easier to use i-Pi or ASE.
