How to put the friction in the comsol???

Hello!
I wonder something.......... i should put some data in the boundary settings of equation system.
But that result was so weird.... i think the results in slip and frition states is not same. but it was
same.... so i wonder what it was happened...

in the case of 2D in the friction state it was working.

i typed some data in only weak of weak menu of boundary seetings - equation.
i wish to know what and where i write more data.

please if you know this solutions, let me know.

Thank you! have a good day!
