Dear Prof. Arndt, Thanks for your quick answer! In my deal.ii (version 8.5.1), the code also fails in the 9th time step. Shall I need to reinstall my deal.ii into the newest version?
For the shortest test code, please give me some time. Because I have deleted about 2000 lines. If I delete some other lines, the error information will change. Thank you!
