We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Have a look here  https://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v241/en/flu_ug/flu_ug_sec_files_data_file_options.html   Looks like it's a Legacy .dat.gz option. 

If you type it 0 in the TUI that may also recalculate the gradients. It's a shortcut to tell Fluent to calculate zero iterations, but may also do what you need. Alternatively it 1 may be a more reliable option. That will not update the timestep - it adds iterations into the current time step.Â
