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 I directly set up the matrix and rhs vector as complex<double> ? Why does step-29 says "*it is often more convenient to split complex valued functions into their real and imaginary parts and use separate scalar finite element fields for discretizing each one of them*" ? Best wishes,
