Hi, I am currently using Comsol to simulate a drop of surfactant spreading on the free surface. But due to the nonlinearity of diffusion equation, I cannot get convergence answer. I am new to CFD. So can anyone give me a suggestion, like change it to Fluent will be better or write your own codes? I really think the problem here is common and hope anyone will give me a reply.

converge, converge error, convergence failure, spreading factor, surface tension
