Question #147820 on DOLFIN changed:
https://answers.launchpad.net/dolfin/+question/147820

    Status: Open => Answered

Kent-Andre Mardal proposed the following answer:
You should be able to use GetPointData().GetArray(). Have you looked at the
name of the variable in the vtu file? It is in ASCII format.

I attach something I did earlier.
