Hello everyone, I encountered a problem during the process corner simulation as shown in the following figure

And received the following prompt:

---------------------------------------------------------------------------------------------------------------------------------------------------

WARNING (EXPLORER-1910): Could not create the directory //.tmp_student1/ in order to store temporary scripts.
The scripts will be stored in the directory /.
Check if user has permission to create these directories.
Alternatively, the Cadence variable
envSetVal("adexl.distribute" "jobFileDir" 'string "<new_path>")
can be set to store the temporary files in an alternate location

These files will be stored in a directory which may be shared by other processes.
Alternatively, the Cadence variable

 Moreover, this problem also occurs when I use ADE XL for simulation,there was no similar problem in the previous simulation,do anyone know how to solve it ?
