Problems with CBC.PDESys demos.

Question

Hello,
I am trying to run few demos of cbc.pdesys-1.0.0
but I have bugs. Maybe somebody could help me ?

1- drivencavity_demo.py

   1- UnitSquare shoulb be UnitSquareMesh

   2- File "PDESubSystems.py", line 628, in __init__
      self.c = assemble(Constant(1., cell=V.cell())*dx, mesh=V.mesh())        
      TypeError: assemble() got an unexpected keyword argument 'mesh'

2- Lshape.py

   1- File "PDESubSystems.py", line 913, in info_red
      if MPI.process_number()==0:
      AttributeError: type object 'MPI' has no attribute 'process_number'

   2- then error 1-2

3- channel.py

   1- File "PDESubSystems.py", line 946, in add_BC
      bc_list.append(PeriodicBC(V, bc))
      NameError: global name 'PeriodicBC' is not defined

4- also it seems that method "tabulate_dofs" used in Walls.py
is not available anymore.

I am running version 1.5.0 of dolfin.

On fenics website, in the page Applications, there is no direct
link to the CBC.PDESys page. Does it mean that the projet is not
maintained anymore ?

Comments

Yes, it is currently not being maintained.

Hi!

CBC.PDESys is on the page Applications again, so does it mean it is being maintained again?

http://fenicsproject.org/applications/

What does "being maintained" mean? Does it mean it is being developed again and possible bugs are being corrected?

Thanks!
