I’m interesting in finding the possibility to define the TestFunction and TrialFunction with different spaces. More specifically, I’m particular interested in using DG to represent a fundamental 1D FVM discretization, to do so, i need to define the TestFunction as constant 1. I tested it in FEniCS but failed.
Is there anyone know if it is possbile to do so in the current FEniCS? If possible, what is the right way to implement?
Thanks a lot!
