  whenever i tried to open solver of my previous version of ansys 2020 r1, i am getting an error message that " FLEXlm Servers: C:PROGRA~1ANSYSI~1ANSYSS~1Shared FilesLicensingstudent.lic
  does not have any licenses for any product. Please make sure
  the license server has been started correctly".
  Even i downloaded new version of ansys 2021R1 by today only, & installed it but still showing error message
  "Unable to spawn node: license not available.
  ANSYS LICENSE MANAGER ERROR:Not enough HPC Parallel licenses 6/4."
  kindly help me

  When you launch Fluent change the number of parallel to 4. We changed the limits in 2021R1 and you look to be exceeding them (6 cores selected). n

  In Student 4 is the limit; in Research or Commercial which your University pays for you can as parallel packs are available to increase as far as you want (KAUST ran on about 200k cores). With a cap at 512k cells 4 cores is good enough for the Student bundle: it's for learning not high end simulation. n
