Hi All,

I am attempting to use the complex branch of Firedrake but I'm having problems - I hope someone can help!

I installed Firedrake using the firedrake-install script from the complex branch, using the command:

python3 firedrake-install --disable-ssh --complex --minimal-petsc --adjoint --slope --install gusto --package-branch ufl complex --package-branch tsfc complex --package-branch PyOP2 complex --package-branch COFFEE complex --venv complex-firedrake

I have activated the correct virtual environment and checked out the complex branch of firedrake:

(complex-firedrake) jshipton@JSMac~/complex-firedrake/src/firedrake $ git branch

* complex

  master

I'm not sure which of the tests are supposed to work on this branch so I just tried the following:

from firedrake import *

mesh = UnitSquareMesh(10, 10)

V = FunctionSpace(mesh, "CG", 1)

and got the error:

Traceback (most recent call last):

  File "test_complex.py", line 4, in <module>

    V = FunctionSpace(mesh, "CG", 1)

  File "<decorator-gen-716>", line 2, in FunctionSpace

    element = make_scalar_element(mesh, family, degree, vfamily, vdegree)

    mesh.init()

  File "/Users/jshipton/complex-firedrake/src/firedrake/firedrake/mesh.py", line 993, in init

    self._callback(self)

    (self.num_vertices(), geometric_dim))

  File "firedrake/dmplex.pyx", line 851, in firedrake.dmplex.reordered_coords

    ELSE:

ValueError: Buffer dtype mismatch, expected 'PetscReal' but got 'complex double'

Did I miss a step or is this currently broken?

I've attached the install log just incase that has any useful information but it looks happy with everything...

Thanks!
