Hi Stuart and CONTAM users,
Do you know how to get steady-state concentration from .sim file? 
I could manually generate separate concentration files from <Export results> shown as below. But is it possible to get this value directly from .sim file? I converted the .sim file into text version but couldn't find the Steady-state concentration. (Might be some silly mistake I made) Or the .sim file just doesn't include the value? Thanks for the help.

Yao,

I’m not sure what you mean by “converting .sim file into text,” and I don’t seem to recognize the format of results you’ve presented.

Nor am I clear on how your PRJ was configured and what exactly you mean by “steady-state concentration”.
The fact that you have “86400” as a time indicates to me that you’ve may have performed a transient simulation.

 

Anyway, there are several ways to obtain results from the SIM file.

See previous posts that address this:

If you are still struggling after reviewing the methods presented in these posts, then it’s best to share your input files (PRJ, WTH, CTM, etc.) to obtain guidance specific to your case.
