CCL:G: Disk space error in DoCrtU when optimizing geometry in Gaussian

 Sent to CCL by: "Maria  Dimitrova" [maria.dimitrova*o*]
 I have a fairly big molecule, the structure of which I would like to optimise in
 Gaussian 16.03. The calculation crashes with the error message "Not enough
 space in DoCrtU". It does not mention memory, so I guess this refers to
 disk space instead of RAM memory. How can I specify another scratch directory?
 Do I need to give a certain amount of disk space when I submit the job through
 Best regards,
