Hello,
I am trying to run code from here 9. Mixed formulation for Poisson equation — FEniCS Project and it does not work. The error
File “demo_mixed-poisson.py”, line 52, in
W = BDM * DG
TypeError: unsupported operand type(s) for *: ‘FunctionSpace’ and ‘FunctionSpace’
Is there an updated version of the same code for the latest stable version (2019) ? Thank you!
