Dear Ivar,
I am trying to solve 2D Marangoni effect due to solute evaporation. I never succeeded. Therefore I tried a different system in which Marangoni stresses come into play due to temperature differences rather than concentration differences. Note that the "diffusion of solute" and "diffusion of heat" have identical physics. I have ensured that I adjusted all the physical constants such that COMSOL is solving exactly that same equations. So far, the system of equations for the "Temperature-Laminar fluid flow" system works perfectly and outputs the expected results. But the "Concentration-Laminar fluid flow" systems does not yield any solution. I am attaching my comsol file, pls help me. Thanks for your time and invaluable service to the community.
thanks
