Saving Projects

Use the File > Save As command to do the following:

• Save a new project.
• Save the active project with a different name or in a different location.

Use the File > Save command to save the active project.

Maxwell has a Save before solving setting located in the Tools > Options > Maxwell (3D, or 2D) Options or Tools/Options/RMxprt Options menu. By default, this is on. However, for efficiency reasons, the project is only saved if it has been modified since its last save.

A prompt appears when you attempt to save a previously versioned file. If you agree to the prompt, the file is upgraded to the Maxwell version in which you are running the software. In this case the file may no longer be compatible with previous versions. If you do not agree to the prompt, the file is not saved, so the file retains the previous compatibility.

If you have a simulation running, you see a warning that if you continue, Maxwell will abort the simulation. If you click OK in the warning, Maxwell aborts the simulation and saves the project.

Path Name Length Issues for Windows

For most Windows programs, the current directory pathname length is limited to 259 characters on startup. Thus, the pathname length of the directory containing installed programs should be limited to no more than 259 characters because double-clicking on an application in Windows Explorer will set the working directory to the directory containing the application when the application is started.

Win32 Long Paths Not Enabled

If win32 long paths are not enabled on the analysis host, then essentially all files are limited to a maximum absolute pathname length of 259 characters. Directories may be limited to a maximum absolute pathname length of about 246 characters.

Win32 Long Paths Are Enabled

If win32 long paths are enabled on the analysis host, then many files are not subject to the maximum absolute pathname length limit of 259 characters. Here is a partial list of files that are still subject to this limit even if win32 Long Paths are enabled:

• Project Files

• Project Archive Files

• Ansys EDB (Electronics DataBase) files: These files are typically stored in the ProjectName.aedb folder.

• The temporary directory and most temporary files. Because some of the temporary files and temporary directories have automatically generated names that may be moderately long, it is best to use a short pathname for the temporary directory.

• Although most temporary files are created within the temporary directory, there may be some temporary files created within the project directory that are limited to a maximum absolute pathname length of 259 characters. As a result, the project file directory pathname should be well below this limit.

To enable Long Path support on Windows, both of the following requirements must be met:

• The application manifest must have the longPathAware setting specified as true.

• Long paths must be enabled on the machine: There are two ways to do this; either may be used:

  Registry setting: HKLM\SYSTEM\CurrentControlSet\Control\FileSystem : LongPathsEnabled=1

  Via Group Policy Tool: The “Enable Win32 long paths” setting is in the folder: Computer Configuration > Administrative Templates > System > Filesystem.
