Hello All, Are the parametres "BROY_W0", "BROY_WMAX" and "BROY_WMIN" not implemented in CP2k yet? I was trying to do a DFTB calculation with Broyden mixing, but none of these variables could be successfully read by CP2k program, although I did input as they appear in the manual. Has anyone ever tried Broyden mixing in CP2k? Thanks, Vince
