export files every timestep or iteration for a convergence-analysis
 

Hello everyone,

I have a question and would like to be happy if someone can help me.

I am simulating a cd nozzle and I am going to make a convergence analyses on some boundaries/lines. To do this, I am trying to export a xy-plot along a curve-length every iteration or timestep. In the Monitoring are only operators in the Report Type like Facet Minimum/Area-Weighted Average on a curve and so on. But I want to plot and/or write a file like when you go to the xy-plot dialog box and click on Write for each iteration/timestep like the picture below.

I tried this with Execute Commands -> define macro but this is overwriting the existing files which includes the xy-plot from the older iteration. I tried also with reading journal-file every iteration which includes commands like plot y ... but this is overwriting, too.
Fluent is not asking to attach the new file to the older file. Ironically if I use Reports and Surface Integrals Fluent is asking to attach or not. But on the xy-plot, Fluent is not asking.

Is there is a way to export a file every iteration/timestep like shown above? The x-coordinates are constant, it's not a dynamic mesh.

Thanks in advance.

With best regards,
Mustafa Cavdir
