I have a very simple example to exercise the Beta feature in ANSYS 2019 R2. That is the Fault-tolerant Meshing.  This has been done by first launching the standalone Fluent program. Don't start Workbench to try this.

If you are on the Student License, you must use this command to launch standalone Fluent.

"C:\Program Files\ANSYS Inc\ANSYS Student\v194\fluent\ntbin\win64\fluent.exe" -r19.4.0 -shortcut

In the Beta feature release, this workflow requires a FMD file format, which you can get by a Save As in SpaceClaim.

 

 Repeat this but add in Boundary Layer of Prism cells.
