When doing ABACUS SCF using mGGA like:

  • RPPSCAN: MGGA_X_RPPSCAN+MGGA_C_RPPSCAN

There will be problem:

 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
                         NOTICE                           
 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
 
 Eigenvalues are too large!
 CHECK IN FILE : OUT.clean/warning.log

                         NOTICE
