  Hello everyone,
  Whenever I try to run a simulation, I get an Error that says "An unknown error occurred during solution,Check the solver output on the solution. Project > Model > Static Structural > Solution"
  I have seen previous topics about the particular type of error but the solutions did not work for me. How do I resolve this?

  often results in the fastest solution time. This mode is recommended

  I see you are using a very old version 16.0 which is not supported officially by us. Is it possible to try a newer version?
  Also, it looks like some data is corrupted in the project as per the message. Have you tried running a simple project?

  You can try renaming the %appdata%\Ansys folder to %appdata%\Ansys.old and then retry again.

  I use an older version of windows hence my reason for this ANSYS model. I use windows 8 but I will try your solution to see if it works.
