Can't add flow volume extraction as per youtube video

I know little to nothing about CFDs, all I want to do as play around with this and get it to work. I watched this video How to Simulate the External Aerodynamics of an Ahmed Body - YouTube but when he clicks on ‘Ahmed body’ he gets an option for “Add geometry operation” → “Enclosure” which I don’t get the option for, which as far as Im concerned is needed to complete a simulation. Any help is appreciated, thanks.


The workflow that you are mentioning is slightly outdated. Make sure to check this page for the updated workflow: How to Create Flow Volume Extraction? | Knowledge Base | SimScale
