After installing Abaqus CAE, you may get the following IOError error message when trying to run the software.
This would require you to run as Administrator every time and may be problematic if you do not have full administrative rights to your workstation. After some investigation, the issue has to do with write permissions to your Abaqus CAE work directory. The default directory is usually C:\Temp
You can resolve this by launching Abaqus from a new directory, one that you have full permissions for. There are a few ways to do this. In this article, I review step-by-step directions for two methods that you can launch Abaqus CAE from a new directory.
The first method is perhaps a bit less popular. This is an example of launching Abaqus CAE from the command prompt after changing the directory to a new folder named “NEW_WORKING_DIRECTORY.” I have also verified that the new directory I will be using has full permissions.
In step 1 of the above picture, I launched the Abaqus Command prompt and changed the directory to a new folder named “NEW_WORKING_DIRECTORY.”
For Step 2, I entered “dir” to get some information about the directory and verify that I have plenty of disk space to run my analysis.
For step 3, I typed “abaqus cae” to launch the software from this new work directory.
After Abaqus CAE launches, we can confirm that my work directory has changed.
A more common way to resolve this error message, is to edit the Abaqus CAE shortcut that you are using to launch in Windows and change the “Start In” directory to a directory that you have full permissions to. For this example we will change the directory to the folder named “NEW_WORKING_DIRECTORY.”
I will outline the steps below. This workflow is the same in Windows 10 and for Windows 11.
This article was a step-by-step guide on how to resolve a fairly common error message of IOError: Permission denied that a user can get when trying to run Abaqus CAE. This typically occures when a new installation of Abaqus CAE or when permissions have been changed on your workstation.
