Content: This dataset includes processed data from two experiments on enzymatically induced carbonate precipitation (2D1 and 2D2), whose raw data is already published in https://doi.org/10.18419/darus-1799 (there named Quasi-2D-1 and Quasi-2D-2).

This dataset contains in detail:

Files for reproducing the simulation results:

the docker container based on the image "gehring2022a.tar". The script script "docker_gehring2022a" can be used to run the docker container. Alternatively, the code is published at: https://git.iws.uni-stuttgart.de/dumux-pub/gehring2022a.

The other files "Files.tar":

a folder for each experiment (2D1: based on Quasi-2D-1 in https://doi.org/10.18419/darus-1799, 2D2: based on Quasi-2D-2 in https://doi.org/10.18419/darus-1799)
