Hi,

I want to run my script on an HPC (NeSI Pan cluster).
When I run my script on Pan cluster with more than 1 cpu, I confront an error saying:

"Input Error: Incorrect ncuts.
DomainPartitioner::partition - too few elements for model to be partitioned
WARNING before analysis; partition failed - too few elements
Process Terminating 1
Process Terminating"

However, I can run a similar model with around 30,000 DOFs on my office computer using parallel processing and 4cpus (the larger model contains almost 800,000 DOFs).
Any idea on this? Is it possible it's due to the NeSI OpenSeesSP compilation (they're using MPI)?

Kindest regards,
Arman

I would appreciate if somebody can answer to this, is it do to Mumps?

looks like there is a problem with their build .. it should only give that message if you have very few elements, i.e. about 1 per processor.

You're right Frank. There was a problem with their compilation and they've fixed it now.
