  Did you check the solution information aka solve.out file in the project directory? What error do you get?

  Thanks for replying. Below is the error. I'm also attaching some images
  
  "The license is currently in use by another application in this Workbench session such as Mechanical or another Mechanical APDL application. You must wait until the other application has finished its task (for example meshing) or manually PAUSE the other Mechanical APDL application "
