Hi everyone;

I am trying to use "partialSlip" boundary on a wall surface which requires the input variable named "valueFraction".

The "valueFraction" is bounded between 0 and 1 with 1 meaning no-Slip and 0 meaning slip. Intermediate value means, we have partial slip boundary condition.

I can see that the governing equation is of form: (1-valueFraction)*___. However, I am not able to fill the blank above.
I came across several posts on this topic but ultimately they were not answered at the end.

I feel the slip length, cell size and valueFraction are related in some way but not sure how.

Can anyone with experience help me in this regard?

Thanks.
