I have several codes using the KSP linear solvers with real numbers. As I understood from the documentation, in order to use complex numbers I have to configure petsc in a different way. The information I failed to find is what does it take to port my current real-based codes to work with a complex-based Petsc version. Is a choice real/complex a transparent one or requires explicit adaptations in the code?
Thanks for any clarifications, Regards, Dominik
