Dear CP2K users, <div>I am trying to run CELL_OPT calculations. </div><div>The calculations start running correctly, but after one or a few steps it stops without any warning or error message. I stops right before the next SCF cycle. </div><div><br /></div><div>This is the part of my input:</div><div><br /></div><div><font face="Courier New">&GLOBAL<br /> PRINT_LEVEL MEDIUM<br /> PROJECT_NAME interface<br /> RUN_TYPE CELL_OPT<br />&END GLOBAL<br /><br />&MOTION<br /> &CONSTRAINT<br /> &FIXED_ATOMS<br /> COMPONENTS_TO_FIX xyz<br /> LIST 256..325<br /> &END FIXED_ATOMS<br /> &END CONSTRAINT<br /><br /> &CELL_OPT<br /> OPTIMIZER BFGS<br /> TYPE DIRECT_CELL_OPT<br /> KEEP_ANGLES .TRUE. <br /> KEEP_SYMMETRY .TRUE. <br /> &END CELL_OPT<br /><br /> &GEO_OPT<br /> TYPE MINIMIZATION<br /> OPTIMIZER BFGS<br /> &END GEO_OPT<br />&END MOTION<br /><br />&FORCE_EVAL<br /> METHOD QS<br /> STRESS_TENSOR ANALYTICAL<br /><br /> &DFT<br /> BASIS_SET_FILE_NAME ./BASIS_SETS<br /> POTENTIAL_FILE_NAME ./GTH_POTENTIALS<br /> <br /> &MGRID<br /> NGRIDS 4<br /> CUTOFF 300<br /> REL_CUTOFF 60<br /> &END MGRID<br /><br /> &QS<br /> EPS_DEFAULT 1.0E-14<br /> &END QS<br /><br /> &SCF<br /> SCF_GUESS RESTART<br /> EPS_SCF 1.0E-07<br /> MAX_SCF 500<br /> ADDED_MOS 1000<br /> CHOLESKY INVERSE<br /><br /> &SMEAR ON<br /><span style="white-space: pre;"> </span> METHOD FERMI_DIRAC<br /><span style="white-space: pre;"> </span> ELECTRONIC_TEMPERATURE 300<br /> &END SMEAR <br /><br /> &DIAGONALIZATION<br /><span style="white-space: pre;"> </span> ALGORITHM STANDARD <br /> &END DIAGONALIZATION <br /><br /> &MIXING <br /> METHOD BROYDEN_MIXING<br /> ALPHA 0.1<br /> BETA 0.5<br /> NBROYDEN 8<br /> &END MIXING<br /> &END SCF<br /><br /> &XC<br /> &XC_FUNCTIONAL PBE<br /> &END XC_FUNCTIONAL<br /> &END XC</font></div><div><font face="Courier New"><br /> &END DFT </font></div><div><font face="Courier New"> .</font></div><div><font face="Courier New"> .</font></div><div><font face="Courier New"> .</font></div><div><font face="Courier New">&END FORCE_EVAL</font></div><div><br /></div><div>The output file just stops like so:</div><div><br /></div><div><font face="Courier New"> Number of electrons: 2980<br /> Number of occupied orbitals: 1535<br /> Number of molecular orbitals: 2490<br /><br /> Number of orbital functions: 6500<br /> Number of independent orbital functions: 6500<br /><br /> Parameters for the always stable predictor-corrector (ASPC) method:<br /><br /> ASPC order: 0<br /><br /> B(1) = 1.000000<br /><br /> Extrapolation method: ASPC<br /><br /><br /> SCF WAVEFUNCTION OPTIMIZATION<br /><br /> Step Update method Time Convergence Total energy Change<br /> ------------------------------------------------------------------------------</font></div><div><br /></div><div>The system is an interface between two solids and the cell contains approximately 400 atoms.
