  Hello,
  I have a user who is experiencing an issue with our ANSYS 2021 R1 OnDemand app on our HPC Cluster. When they set up system coupling it will crash and the allocated job will be killed, even if it has more time allotted from our job scheduler. Our OS is CentOS 7 and our job scheduler is Slurm. When we attempted to duplicate the issue ourselves, we experienced the same crash and captured the logs for it. For reference, it was allocated 8 cores and 256 GB of memory.
  Is this particular error fatal? The gpus were set to 0 and we're wondering if gpu dependency is in a setting we're unaware of?

  Hello,
  May I know if this is for a particular project or in general system coupling projects fail? Does it also occur while running software, for example, Fluent?
