Navier slip Boundary condition

hi all,
I am trying to implement navier slip boundary condition to wall . I used the below mentioned link :
http://www.tfd.chalmers.se/~hani/kur..._corrected.pdf

I have slightly modified the code mentioned in the link to work with OF8 version however when I ran the test case the results are different compared to what is mentioned.

nonLinNavSlipGenNewtonianRelaxationFvPatchField.C

any help would be highly appreciated.

Hi Irwin,

I don't have any experience with the Navier slip boundary condition, so I cannot offer my expertise. However, I did come accrss an implementation of this boundary condition in Rheotool: https://github.com/fppimenta/rheoToo...ons/navierSlip

It also offers a great manual. Although I am not sure if they describe the boundary condition.

Thanks a lot, can you provide some information about the cases where this have been implemented.

When searching for the 'Navier slip' term in the Rheotool repository, you can find an example case.

Thanks, I tested this boundary condition with the different solvers of rheotool. Its working fine for rheoFoam but for rheoInterFoam it fails . Can you share some information about this .

Thanks
