Accumulated timestep&coefficient loop
 

Hello everyone,
I ran some cases by CFX and set some monitor points to get their variables. I set the software record these variables every timestep.

However, when I checked the result, I found that the data was very strange. First, as the x axis set as "accumulated timestep", the value should be integer. In my case, some of the value is decimal, such as “4210 4210.5 4211 4211.5 ...”(Fig1). Second, when I exported the variables to ".csv" file, I found that for some timesteps, they have more than one value and there is a item"coefficient loop"(Fig2). I didn't set this value when I set the ".def" file.

Hope that anyone can help me, it is so confusing.

Your monitoring data contains the iterations (Coefficient loops) within a timestep as well. Default is that it only plots only the end value of the timestep.
This is because in your Output Control, you have selected "Monitor Coefficient Loop Convergence". If you turn this off, then you will go back to the default settings.

Yes! That's exactly the reason，thank you very much!^_^
