  1.I am running large cases (10GB size) with polyhedron cells (45M). I often have problems while opening the case files,
  
  Usually it gets stuck on 'building mesh' process.
  
  2. During transient simulations, after writing large data files (15GB) for every 100 timesteps data file write process freezes or never completes, I have to kill the job and run it again.
  
  PS: I run my jobs on multiple nodes (5 of them) each with 20 Xeon cores and 128 GB RAM , I dont think its a memory issue
  
  Help is much appreciated
