  I'm always getting this error after each session. What to do? Even I tried a couple of solutions mentioned in the community. But, they did not solve my issue.

  It usually means you've made a change and Fluent didn't fully clean up what you did. What models are on, and are you using any UDFs or scripts. If you use the "list changes" option can you see any "blank" entries in the list of modified settings?
