PETSC Error in generate_mesh

6 months ago by
I had this piece of code, which used to work, but recently when I wanted to run it again it didn't anymore.

I have identified the error to happen when running the generate_mesh function. It seems to be a general thing for my installation, which has broken somehow. A simple code snippet like the one below breaks:

from dolfin import *
from mshr import *

R = Rectangle(Point(0,0),Point(1,1))

mesh = generate_mesh(R,10)​
It throws the following tantrum
[0]PETSC ERROR: ------------------------------------------------------------------------
[0]PETSC ERROR: Caught signal number 11 SEGV: Segmentation Violation, probably memory access out of range
[0]PETSC ERROR: Try option -start_in_debugger or -on_error_attach_debugger

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 59.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

Any idea what could be causing this?

domain is not defined in your example.

My bad, there was previously a line: domain = R, which I had removed, when I copied the code here. Forgot to change the domain variable to R in generate_mesh()
