Hello Fang,

I recommend you to use the newest feature in 2023 r2 fluent version called the water corrosion pre tool option. I have attached the user guide link where they have clearly mentioned on how to set up the case and run the simulation. 

18.1. Modeling Species Transport and Finite-Rate Chemistry (ansys.com)- Refer 

18.1.4.7.2. Procedure for Setting Corrosion Simulations using the Water Corrosion Pre Tool

I hope this helps you.

Thanks,

Chaitanya Natraj
