Deal, all

I am working with marangoni effect.

From : www.comsol.com/showroom/documentation/model/110/

I think there are two methods to solve this problem

with weak formulation or with boundary stress at open boundary.

But after solving both cases, I found out the two results were different.

Does anyone can how to treat this problem?

Beat regards.
