Dual integrators missing serialiser
Hello,
I started transitioning to the 3.0 release from 2.1, and I came upon this issue when running some simulations using the ac-navier-stokes solver. I seem to have fixed it by importing the serialiser in the pyfr.integrators.pseudo.base file and then instantiating the object (self.serialiser = Serialiser()) in the __init__ method of the BaseDualPseudoIntegrator class. It seems to be working now and the printed data looks OK.
I’m not sure what unexpected behaviour this could cause (I’m new to this software and not confident in my bug fix), but I wanted to bring it to your attention.
Thank you
