How to define Robin boundary conditions in a equation based modelling interface?

Please login with a confirmed email address before reporting spam

I want to have these type of boundary conditions,

u=-du/dux, at x=1 and u=-a*du/duy, at y=1, where `a` is a parameter.

How can I input these conditions?

Thanks
