Hi all,
I am working on Boussinesq equation. The notebook can run perfectly for only 0.6 steps and then the calculation starts running slowly after 0.7. All boundary conditions seemed fine. I am unsure if I used the correct method to solve this problem. This is the method I am currently using.
I have tried several methods. Unfortunately, it does not work. I can't figure out the mistake. Please let me know if you have any suggestions. Thank you very much.
