Dear all, I wish to try in qe the functional HLE17 which is included in libxc (with the name MGGA_XC_HLE17); but I do not see any reference to it in the Modules/funct.f90 file. Would this be possible? Regards, -- José C. Conesa Instituto de Catálisis y Petroleoquímica, CSIC Marie Curie 2, Madrid, Spain www.icp.csic.es Tel. (+34)915854766
