Good day. I am currently working on my master thesis on Microbially Induced calcite precipitation in OG6-phreeqc solver. I would to know if there is any benchmark case which solves the porosity reduction and Kozeny-Carman equation in OGS6.
Thanks a Lot Dr. Vanessa for this. I still need to figure out how I can link my phreeqc calculation with the porosity, so that the porosity is reduced at each step and can be linked to Kozeny-Carmen equation.
At the present moment the merge request is still open. So, we will need to wait few days. If you have problems with your simulation just let us know, we will try to help you @renchao.lu

As indicated by @lurpi, the model is still not in OGS master, either you compile from the mentioned “point” or you wait until this is done, which probably will not take too long.
Hello Dr. Vanessa,
I downloaded the latest OGS 6.3.3 version and the corresponding Carman kozeny benchmark, When i compare the results of the benchmark case with kozenycarmen permeability and benchmark case without permeability modification, I am unable to find any changes. My comparison was between the darcy velocity of the two cases.
Hello Dr. Lu and Dr. Vanessa,
I am trying to implement the Kozeny-Carman equation into my reactive transport model but I am unable find a way to link the IPHREEQC calculation and the Kozeny-Carman permeability update, can you please help me with this. The Benchmark case “Contracer” has Kozeny Carman permeability update in it but I am unable to find the modified permeability in it.
