Hello,
Running a big problem (1,601,777 elements) on 100 processors. I am using a
DistributedMesh. At some point, I call
MeshRefinement::refine_and_coarsen_elements() to do AMR, but I get this
assertion error (running in debug mode):
Assertion `min_id == node->processor_id()' failed.
min_id = 11
node->processor_id() = 57
Assertion `max_id == node->processor_id()' failed.
max_id = 57
node->processor_id() = 11
Assertion `max_id == node->processor_id()' failed.
max_id = 57
node->processor_id() = 11
I also obtain traceout files with numbers: traceout_57_85461.txt
traceout_11_104555.txt traceout_8_142118.txt. Their content is similar and
looks like this:
[New LWP 142203]

Are there other things I can do to debug this?
Thanks
