[FLASH-USERS] Changing the reflective boundary condition to a periodic one causes problems in the calculation

[lizy]

Dear Flash Developer
I replaced the reflective boundary conditions with periodic boundary conditions on the upper and lower boundaries of the cylindrical calculation domain, and the following error occurred. What should I do?
  I am grateful for your answer！
