  Unable to use all cores eventhough 3 HPC packs are available. While solving parallely following error is displayed. "Failure feature 'DSO Engine' specified in li preferences is not avialable. Insufficient DSO engine. Flexnet Licensing error-4,132 ".
  
  Could anyone please suggest what can be done.
  
  Note: Platform on which ANSYS EM suite installed is Linux(RHEL 7.6)

  please be more specific. what project and solver do you speak of?
  
  in hfss try "use hpc pool", "legacy off". for Maxwell should be the same. Number of cores is multiple of workers number.
  
  I am not familiar with setting the distribution style. In the past it was simple one rank distribution and just worked by the number of licenses.

  Hi,
  
  Thanks for your reply.
  
  we cant able to use full cores when we are trying to solve parallel frequency sweep.
  
  (Parallel frequencies being solved should be equal to number of task specified in hpc setup).
  
  Hereby I have attached some screenshots for your reference

  that's what I say. I may be mistaken, but I had impresion that #cores=N*#workers. Am I wrong? BTW, In ver 13 there were no "workers", number of nodes required an equal number of HPC licenses, if I am not mistaken. now it got more complicated
