Hi Dana,

Which version of the standalone fluent application you are using?

If you can use the v231 fluent standalone application but not through workbench, then follow the below steps:


Close all the Ansys applications.

Go to Startà search “Product and CAD Configuration 2021 R2” and run it as admin.

Follow the below steps: (while configuring products and unconfiguring products “select all” option)

  1. Install Required Prerequisites.
  2. Unconfigure Products & CADs.
  3. Configure Products & CADs.

Rename the Ansys folder to Ansys.old (%appdata%) and .ansys to .ansys.old (%temp%) 

Launch the application again.

If you are not able to use the standalone fluent v231 application then it’s a licensing error.

Let me know if the above solutions work for you.
