Change of particle size in gas-solid chemical reaction

Hello, I’m doing the simulation of gas-solid reaction found that particle diameter is obtained by post-processing is the overall change, because I set at the bottom of the entry into the co2, so I want to get the particles should be as the co2 gas into the changes, before I asked the question, has been in the heart of the initial conditions of gas to air filling, But after running the program or wrong, excuse me, what solution? Thank you

This looks like the same question as Chemical reaction particle diameter change - #4 by cgw where you said “the problem has been solved”. If this is a new question, please try explaining more clearly.

Hello, thank you very much for your always help, I ask this question before, you also gave me help, I try to join in the initial conditions the air, only then in the post-processing, I find the result is still as before, so I want to ask what place is wrong, please set or any other reason, thank you once again
