Not of this video, no. This one ends before showing the final results to encourage students to solve the problem themselves. The final result often becomes an eye-opener for students that I (or one of my Teaching assistants) discuss with them
I do not want to be too explicit here as my students are expected to carry out the calculation, but I can say that you're incorrect: There is no flow, only diffusion.
At our department we do introduce students in simulating with Comsol as part of some of our regular courses for engineering students. Those course are, however, only available for student enlisted at the Faculty of Engineering, Lund University. However, I'm sure there are training courses in Comsol available elsewhere.
Sorry, no. Our time is very limited and we rely heavily on external research funding for specific projects. Also, I don't think we have anyone employed at present who is working on crystal growth. For more info on research done at Lund University I would recommend you to search for publications through portal.research.lu.se/portal/en/
