aerba, Thank you very much for your reply!

Unfortunately, I don't speak English very well, which is why I may have phrased my question incorrectly.

My question was that the function OPTGEOM does not work correctly with RUNCONFS. I had already tried the steps you suggested.

However, I was able to figure out the problem. For geometric optimization, I just needed to specify the keyword more correctly:

CRYSTAL 0 0 0 194 3.065 17.656 4 22 0 0 0.5 14 0 0 0.75 22 0.666666 0.333333 0.364919 6 0.333333 0.666666 0.427507 SCELCONF 1 0 0 0 1 0 0 0 1 RUNCONFS ATOMSUBS 22 273 OPTGEOM MAXCYCLE 500 ENDOPT END END

I'll leave it here, maybe it will be useful to someone in the future.

Nevertheless, thank you very much for your responsiveness

Thank you!
