我在学习使用CP2K中的dimer计算过渡态,进行了一些试算,但总出现下列错误:
- *******************************************************************************
- * ___ *
- * / \ *
- * [ABORT] *
- * \___/ BFGS method not yet working with DIMER *
- * | *
- * O/| *
- * /| | *
- * / \ motion/bfgs_optimizer.F:147 *
- *******************************************************************************
- ===== Routine Calling Stack =====
- 8 geoopt_bfgs
- 7 cp_rot_opt
- 6 cp_eval_at_ts
- 5 cp_eval_at
- 4 cp_cg_main
- 3 geoopt_cg
- 2 cp_geo_opt
- 1 CP2K
复制代码 我已经将优化算法改成了CG,不知道为什么还是出现BFGS的错误,请教大家该如何正确使用dimer?
我的CP2K版本为4.1版,输入文件如下:
