Hello Rania Elsebai, review your assembly to see if there are any existing orientations named "_none." If there are, you'll need to rename or remove them. Try changing the name of the new orientation to something unique. Make sure it does not conflict with any existing names.
You are encountering an error in Abaqus related to orientation definitions, indicating that the name "assembly _none" has already been used for another orientation. To resolve this issue, you can follow these steps:
Check Existing Orientations: Go to the Orientation section of your model and check if the name "assembly _none" exists.
Rename Existing Orientations: If such a name exists, rename it to something unique.
Create a New Orientation: When creating a new orientation, ensure to use a unique name.
Check for Typos: Make sure there are no typos or extra spaces in the orientation name.
Restart Abaqus: Sometimes, restarting the program can help resolve the issue.
