Hi,

Explanation of the Situation:
I made a transient Fluent simulation which includes small time steps and a long time period to simulate.



I created an expression and variable (minimum species concentration in an area) and plotted this expression vs time as a chart in CFD-Post.




The issue:
That does work well, but it takes forever (1-2h) to render the chart. I think the main issue is that CFD-Post goes through my 200,000 timesteps and calculates the expression.


What I would like to do:
I have a few more simulations to analyse and I really only need like 100 points between start and end time in the plot. Is there a way to tell the chart in CFD post how many points to use?



Kind Regards

Kosch
