请问如何暂停ABAQUS作业？ 30

如期，用的是频率和随机响应分析步，运算中途输入abaqus suspend job=job-1显示：

Abaqus Error: Could not determine the Client ID of the job you requested (job-1)

a) Please try issuing the suspend command from the same directory

   from which the job was started.

b) Please verify that the job is still running.

任务名、工作目录都没问题，任务还在算，请问这个是怎么一回事

另外，暂停任务有没有在界面里的选项
