  Hello, I’m using ANSYS Fluent '2020 R2'. I’d like to know how to set up the 'Pseudo Time Method' when using the SIMPLE method.
  Also, the link below shows how to set up the Pseudo Time Method in the 2022 R2 version, but where can I find a similar manual for the 2020 R2 version? As shown in the attached image, there is no relevant item for the Pseudo Time Method setup in the 2020 R2 version.

  It's an option in the Pressure Based Coupled Solver. So change from SIMPLE to PBCS. Note, we're just releasing 2025R1 so you may want to update the software.
  Click on Help in the Fluent solver, and you may get the local install of Help, otherwise you may get the online version. I use may rather than will as I don't know how many previous version sets are on the system and there was a change from an automatic local Help install to an on demand with online around that time.
