Hi all,

hope you are all doing well in these tough times.

I have pipe flow with non slip wall boundary condition. currently using the bouzidi for round surfaces. I have a viscous fluid going into the pipe and exiting with a certain laminar reynold number. what Im looking for is the velocity profile near the wall. and for this to be close to the real application, i need to apply some sort of friction factor between the wall and fluid. is there some kind of partial slip boundary condition available in openlb?

As soon as move i away from the wall, the velocity graph starts rising. i was hoping with the friction introduced, my velocity near the wall would take longer time to start increasing/changing.

any advice would be appreciated
