Hint

** Working directory **

  • A working directory is a folder whose name is the name of the file opened in the main window plus a suffix.

    • ** The suffix varies depending on the type of solver. **
    • For example, in the case of Gromacs, if the file opened in the main window is aaa.gro and the suffix is _gmx_tmp, the working directory will be named aaa_gmx_tmp.
  • It must be in the same hierarchy as the file opened in the main window.

  • Processing continues in the working directory of the same name even when continuing jobs, but by default the backup of the working directory of the previous job is created just before the continuation job is executed.

    • The name of the backup will be the one with the smallest number in the range where duplicate names do not exist. For example, if the working directory is aaa_gmx_tmp, it is aaa_gmx_tmp1.
    • ** Directories without numbers are always up to date. **

Job is run through Winmostar Job Manager.
