I want to delete the ball outside my wall and not understand how to do it.  
The image of the geometry is attached with the message.

Hello @ShivamPandey,  
If you have a geometry object that you created your walls from you can use the following command:

`ball delete range geometry-space <'geometry set'> outside`

where _‘geometry set’_ is the name of the geometry set
