  hi
  
  when I load a saved Case or Data file and run the calculation to continue previous calculations. it iterates very slow!
  
  but when initialize and start the same from first there is no problem!
  
  Ansys 19.3
  
  CentOS 7.4
  
  10 Cluster node
  
  totally 160 core/320 thread
  
  I tried this method too: stop at end of iteration> save the case and data > without exiting fluent. read the files again (case,data,udf no changes) and continue to calc.... but the problem exists.
  
  3 times I restarted the clusters and head-node.
  
  10 times I closed the fluent and run again.

  What does the UDF do?
