Error in vertical advection in CMAQv5.0.2

Hi
I ran domain 1, but it didn’t go all the way.
It has to run from June 15 to July 31, but it only run until June 19.
I checked the log file and got this error.

I don’t know why I got the error.
Someone could help me how can I do? Thanks in advance.

Since this is an entirely different error from your previous post, it makes sense that you created a new thread for it.
However, if you do so, you should put more complete information in the new thread, so that it can help other users in the future.

For this error, try the solution previously suggested by @fliu : reduce CTM_MAXSYNC to something less than 12 minutes (720 s). Maybe try 300. I might restart the model and run for just one day to get past the trouble spot.

I have also encountered the same issue and attempted to adjust the values of CTM_MAXSYNC or CTM_MINSYNC, such as 720, 360, 300, 240, and 120. However, these adjustments did not resolve the problem.

CMAQv5.0.2 was released in spring 2014, more than 9 years ago. You are not very likely to get detailed support for such an old version.
Try your case with CMAQv5.4. If in fact you are using CMAQv5.4, please post a new thread and provide details on your modeling case. See the “Please click here to read tips before posting” link at the top of the screen.
