No constructor defined for UnitDiscMesh

[Antoine Falaize]

Hi all!

With a previous dolfin version, I used something like the following code to generate a disc mesh:

mesh = dolfin.UnitDiscMesh(comm, 100, 2, 2)

With the code below in dolfin v2018.1.0

import dolfin
print(dolfin.__version__)
comm = dolfin.MPI.comm_world
mesh = dolfin.UnitDiscMesh(comm, 100, 2, 2)

I have the following error:

2018.1.0
Traceback (most recent call last):

  File "<ipython-input-2-b50ace5105c7>", line 4, in <module>
    mesh = dolfin.UnitDiscMesh(comm, 100, 2, 2)

TypeError: dolfin.cpp.generation.UnitDiscMesh: No constructor defined!

Any tip on using UnitDiscMesh now?

Use UnitDiscMesh.create (see poisson-disc demo).

This works. Thank you
