Hello,
I just ran the auto-adaptive-poisson demo and received the following output
and error. Initially, I received a similar error that suggested I set
"allow_extrapolation" to true. I did this, and now receive this error. I am
running on FEnICS/DOLFIN 1.2.0 and python 2.7. Any help would be much
appreciated.
Regards,
Ben
