I have seen such problems already, so it might be systematic, but I'm not sure what are the exact circumstances that trigger this problem.

Try:

make clean all

in the Firedrake source directory.

Subject: [firedrake] missing 'comm'

 

Dear Firedrakers,

  Upon calling

mesh = IcosahedralSphereMesh(1.0,3,2)

I get an error,

Traceback (most recent call last):
  File "dcmip_3-1_linear_advection_triangle_bdfm1.py", line 31, in <module>
    extrusion_type="radial")
  File "<decorator-gen-274>", line 2, in ExtrudedMesh

AttributeError: 'module' object has no attribute 'comm'

Is this another petsc4py issue?

cheers
