Dear Cp2k community<div>I am a novice to cp2k software, and i have been trying to optimize a structure using cp2k but after 200 iterations it gives this result:</div><div><b> *******************************************************************************<br /> *** BRENT - NUMBER OF ENERGY EVALUATIONS : 1 ***<br /> *******************************************************************************<br /><br /> -------- Informations at step = 200 ------------<br /> Optimization Method = SD<br /> Total Energy = -4001.5866174143<br /> Internal Pressure [bar] = 120.9667651938<br /> Real energy change = 0.0000065669<br /> Decrease in energy = NO<br /> Used time = 215.869<br /><br /> Convergence check :<br /> Max. step size = 0.0000000000<br /> Conv. limit for step size = 0.0030000000<br /> Convergence in step size = YES<br /> RMS step size = 0.0000000000<br /> Conv. limit for RMS step = 0.0015000000<br /> Convergence in RMS step = YES<br /> Max. gradient = 0.0011394985<br /> Conv. limit for gradients = 0.0004500000<br /> Conv. for gradients = NO<br /> RMS gradient = 0.0001518928<br /> Conv. limit for RMS grad. = 0.0003000000<br /> Conv. in RMS gradients = YES<br /> Pressure Deviation [bar] = 20.9667651938<br /> Pressure Tolerance [bar] = 100.0000000000<br /> Conv. for PRESSURE = YES<br /> ---------------------------------------------------<br /><br /> *** MAXIMUM NUMBER OF OPTIMIZATION STEPS REACHED ***<br /> *** EXITING GEOMETRY OPTIMIZATION ***<br /></b></div><div><br /></div><div>This occurs in all cases where I am taking a metal organic framework, but the optimization is complete in case of small molecules and is fine.</div><div><br /></div><div>I have also attached input and xyz file below</div><div><br /></div><div>Can anyone suggest me a possible suggestion for the COMPLETE GEOEMTRY OPTIMIZATION.</div><div>Any help will be highly appreciated. </div><div>Thanks and Regards</div><div>Kusum (INDIA).</div>
