Dear Dr. Bangerth, Thank you very much! I found step-62 yesterday and I have compared the difference between them. I want to write two versions and compare their CPU time to get an exact result. Best regards, Yuesu On Sun, Aug 16, 2020 at 7:19 PM Wolfgang Bangerth wrote: > Yuesu, > > >I

Yuesu,   I am adding an absorbing boundary condition like step-24 did in the frequency domain, in which the time derivative gives a complex term.  I also found the complex acoustic wave problem step-29 which splits the complex wave function into two real parts.   What I want to know is what
