The low level error here is a common one: someone is trying to ask DistributedMesh for an element which does not exist on the semilocal (local plus ghosted) part of the mesh. The high level error here could be anything from anywhere; there's no way to tell without a stack trace, preferably with enough debugging options turned on to give us line numbers too. I'd very much appreciate a stack trace; some times these errors are easy to fix as soon as you know where in the code they're coming from. If the fix isn't obvious, but you can boil it down to something small enough to add to the MOOSE test suite, I'd appreciate that too. I've been bug hunting based on test suite failures with --distributed-mesh on various numbers of processors; MOOSE is just too big for me to audit the entire code so I've been relying heavily on test coverage. If you're using DistributedMesh then you definitely want to stay up to date with the newest MOOSE devel/HEAD; I've put a ton of fixes in there over the past month. Let me know your GitHub account name and I can ping you when I'm adding new PRs; the DistributedMesh compatibility bugs are getting fewer in number rapidly but they're not all sorted out yet. You probably want to be using the libMesh master/HEAD too, unless you're using curved elements, for which there seems to be a recent regression that I haven't yet fixed; some of the DistributedMesh bugs that MOOSE picked up were really bugs at the libMesh level which I simply had never managed to trigger with the libMesh or GRINS test suites. --- Roy ------------------------------------------------------------------------------ Announcing the Oxford Dictionaries API!
