Hi Thanks for your reply. I will look into the porous jump ans see if i can use that. 


Is there any way of me getting more detailed help, I am kind of stuck with these divergence. 


the brown volume is solid in the geometry itself, not fluid, and this is representing the debris. 

I have used another model as well using the whole basket volume as the porous media, and not the thin wall. I am still getting divergence.
