Hi

To learn ogs6 I download the following Benchmark-Project

> **[ogs-data/Parabolic/LiquidFlow/Unconfined\_Aquifer/BC\_BC\_RECHARGE at master ·...](https://github.com/ufz/ogs-data/tree/master/Parabolic/LiquidFlow/Unconfined_Aquifer/BC_BC_RECHARGE)**
>
> WARNING: This repository is a mirror of test data from OGS source code. See link: - ufz/ogs-data

When running it with ogs-6.3.0-Windows-10.0.14393 it claims “Could not find phase name ‘Solid’”. Obviously, these project-files do not match the used ogs-exe-version?

Thank you in advance!

Best regards

The BC\_BC\_Recharge benchmark is a LiquidFlow process. The media specification was changed after the release of ogs 6.3.0. Can you use a more recent version?

Yes, when building ogs6 from source, it works. Thanks!
