Hello I have a question about parallel, I am trying to use parallel to fasten the speed, and I have set parameters[‘ghost_mode’]=‘shared_facet’ and run the code with “mpirun -np 2 python3 demo.py”, but from the output, I got two copies of the same solution, does anyone know why? Thanks!

FeniCS Parallel output two copies of solutions?
