Dear all,
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 if
Dear Dr. Bangerth,
I tried a few levels of the tolerance, 1e-3, 1e-4 ,1e-6 and 1e-8. 1e-3
converged because that is in the same level with the solution. Error occurs
below 1e-4. I have tried the Jacobi preconditioner instead of SSOR in the
single thread CG version, it converged as well.

Yes, in exactly the ways the error
