There is a rainfall example in FLAC2D9.3: [Rainfall on a Slope (FLAC2D) — Itasca Software 9.3 documentation](https://docs.itascacg.com/itasca930/flac3d/zone/test2d/ExampleApplications/FromFLAC/16RainfallSlope/RainfallSlope.html?highlight=rainfall)

Can you please convert it for version 9.0 ? I found it totally different. And the pdf I mentioned is from the same example.

This model used the new fluid feature that started from version v9.1. We cannot use v9.0 for this example. Please upgrade your FLAC3D to the subscription version, so you can use up to the newest version (now v9.4).
