请教各位大侠,机子2G,castep 计算一个20多个原子的晶胞(有实验晶胞参数),选择优化晶胞后,优化一直不能正常结束,晶胞参数构型偏离都很大,总是出现如下问题:
Forrtl: severe (170): Program Exception - stack overflow
Image PC Routine Line Source
castepexe.exe 00A98BA7 Unknown Unknown Unknown
或者 Out of RAM for wvfn_slice%realspace_coeffs in wave_recip_to_real_slice,
怎么回事啊?优化多次,改小cutoff energy,收敛精度,K-point,调整empty band or smearing 值都不行,请指点一二,不胜感激啊!
