      ANSYS Staff are not allowed to download attachments. You could copy past the output in the textbox. Also, After you open workbench again what do you see. Is the solution marked completed?
      Regards Ishan.

      The solution for the current simulation was performed using 4 cores.
      The parallel performance of this simulation on this hardware indicates
      that this simulation would benefit from using additional CPU cores.
      Consider using more CPU cores, which may require additional HPC
      licenses, when running this simulation again on the same hardware.

      Additionally, the solution is not marked as completed in Ansys workbench. The lighting bolt icon remains next to the solution step in the transient thermal workflow after the calculation concludes, as mechanical crashes shortly after completion.
