hello,
I am working with marangoni Bc but the results I am getting is not satisfactory.

mu*du/dy = A*dT/dx + B * dC/dx

A and B are constant, v = 0;

Can anybody please tell me how to apply this boundary condition properly. I am attaching the file of streamlines also, the flow is developing and also attaching the solver and boundary condition library.
I am running it in openFoam 5. It is 2D square cavity with temperature and concentration given to the side walls.

thanks.
