Dear All
Do you know how to impose such a boundary condition in COMSOL for a simple flow in a channel?
I want to impose u=du/dy at the lower wall of the channel (for example at y= -1m)
(u is the velocity)
((((I mean, I want to relate a function (like velocity) to its derivative during the solution !))))
Best.
