WebWithout seeing the output from cp2k its hard to tell. But I assume your SCF does only converge slowly. There are several things you can try: EPS_DEFAULT 1E-14, MAX_SCF 30 and make use of the &OUTER_SCF section. – Fabian Nov 18, 2024 at 7:13 Thank you, I will try that. I am starting to suspect the same. Web“CP2K is a program to perform atomistic and molecular simulations of solid state, liquid, molecular, and biological systems. It provides a general framework for different methods such as e.g., density functionaltheory (DFT) using a mixed Gaussian and plane waves approach (GPW) and classicalpairandmany-bodypotentials.”

WebCP2K evaluates the convergence using 4 different criteria: The calculated displacement for the next step must be essentially 0: Conv. limit for step size = 4.50000000E-004 The root-mean-square (RMS) of the calculated displacement for the next step must be also essentially 0: Conv. limit for RMS step = 1.50000000E-003 http://bbs.keinsci.com/thread-36399-1-1.html brightspeed fiber internet reviews

"Web很多参数都可以影响CP2K的计算精度。下面我将介绍我所知道的参数。 3.1.1 晶胞的大小 CP2K只支持Gamma点的计算，没有K点。因此，计算中必须使用足够大的晶胞。如果晶胞太小，部分基组函数就会超过晶胞的边界，导致重叠矩阵求逆过程出现问题，计算就会不可靠。 " - Cp2k cell opt
